INTRODUCTION
Heavier group 14(II) complexes with a formal oxidation state of +2 often consist of a vacant orbital and a lone pair of electrons on the group 14 centers. As a result, they display both electrophilic and nucleophilic characters, leading to Lewis ambiphilicity. These electronic properties should enable heavier group 14(II) complexes to display reactivity that closely resembles that of transition metal complexes in the area of catalysis.1 It was evidenced by Jones et al. that the two-coordinate (amido)(hydrido)germylene and -stannylene [Ar*-(iPr3Si)NË H] (E = Ge, Sn; Ar* = 2,4,6-iPr{C(H)Ph2}2C6H2) are efficient transition-metal-like catalysts in mediating the hydroboration of unsaturated compounds, due to their far more reactive EII−H bonds in comparison with classical EIV−H bonds.2,3 In addition, the two-coordinate GeII and SnII centers preserve their Lewis ambiphilic characters, which enable the σ-bond metathesis, oxidative addition, and reductive elimination processes in the catalyses. Moreover, research
groups of Wesemann and Zhao showed that the base-stabilized germylene and stannylene compounds [AriPrË C(H)(Ph)PPh2] (E = Ge, Sn; AriPr= 2,6-(2,4,6-iPr3C6H2)2C6H3) and [HC{C-(Me)N(Ar {C(CH2)N(Ar)}Ge:] (Ar = 2,6-iPr2C6H3) can catalyze the hydroboration of carbonyl compounds with the aid of the noninnocent ligands, respectively.4a,b Furthermore, Power et al. used the methoxystannylene precatalyst [{ArMesSn(μ-OMe)}2] (ArMes = 2,6-Mes2C6H3, Mes = 2,4,6-Me3C6H2) to catalytically dehydrocouple amine-borane adducts.4c
Similarly, silicon(II) compounds with a formal oxidation state of +2 such as silyliumylidene cations (RSi:+,R=supporting ligand) and hydridosilylenes (R(H)Si:) can show transition-metal-like reactivity in the area of small molecule activation.5 For example, Inoue et al. showed that the Nheterocyclic carbene (NHC)−arylsilyliumylidene cation complex [ArMesSi(IMe)2]+ (IMe = :C{N(Me)C(Me)}2) can reduce CO2 to form CO and activate the C−H bond of phenylacetylene.6 Moreover, Kato et al. illustrated that the basestabilized (amido)(hydrido)silylenes underwent the reversible oxidative addition of SiIV−H and PIII−H bonds at room temperature, in addition to the uncatalyzed insertion of the SiII−H bonds with unsaturated C−X bonds (X = C, N, O, etc.).7 However, catalytic organic transformations mediated by
silicon(II) compounds surprisingly remain unexplored. It could be possibly due to the supporting ligands in a silicon(II) compound, which impart kinetic and thermodynamic stabilization effects on the highly reactive silicon center.8 As a consequence, its Lewis ambiphilic character is not pronounced and the high catalytic potential of a silicon(II) compound is suppressed. To the best of our knowledge, only one example of silicon(II) compounds shows catalytic capability, whereby Jutzi et al. used the cyclopentadienyl silyliumylidene cation [Cp*Si]+ (Cp* = C5Me5) to catalyze the controlled degradation of oligo(ethylene glycol) diethers.9 In this context, it is imperative to develop a strategy to activate the catalytic ability of stable silicon(II) compounds, which would greatly advance sustainable catalysis due to the high abundance and nontoxicity of silicon.
Recently, we described the synthesis of an NHC-parent silyliumylidene cation complex, [(IMe)2SiH]I (1, Figure 1), and its transition-metal-like reactivity in functionalizing the orthoC−H bond of fluorobenzene.10 Considering the chemistry of the above-mentioned base-stabilized silyliumylidene cations and hydridosilylenes, it is anticipated that 1 could be a promising candidate to catalyze organic reactions due to its dual functionality: SiII cation and reactive SiII−H bond. In this context, we were highly interested in investigating its catalytic capability. Herein, we report the NHC-parent silyliumylidene
cation-catalyzed chemo- and regioselective hydroboration of carbon dioxide, carbonyl compounds, and pyridine derivatives (Figure 1).
RESULTS AND DISCUSSION
The catalytic ability of the NHC-parent silyliumylidene cation complex 1 toward hydroboration of CO2 with pinacolborane (HBpin) was first examined, considering that nonmetal compounds have been rarely used as homogeneous catalysts for such reactions; the obtained turnover frequencies (TOF) and selectivity are often low, leading to a mixture of methoxyborane [pinBOMe] (2b) and diborate ether [(pinB)2O] (2c). To begin with, there was no reaction between CO2 and borane (HBpin, BH3·SMe2, HBcat) in C6D6 at 90 °C. However, in the presence of 1 (10 mol %), the reduction of CO2 with HBpin in C6D6 at 90 °C was extremely clean, resulting in the formation of the formoxyborane [pinBOC(O)H] (2a, reaction time: 0.08 h, yield: 94%, TOF= 113.2 h−1; reaction time: 0.17 h, yield: 98%, TOF = 58.7 h−1; Scheme 1; see the Supporting Information, Table S1), along with a trace amount of the diborate ether 2c (yield: <2%). No other identifiable boron-containing products such as methoxyborane 2b were found in the reaction mixture when increasing the reaction time or temperature. Moreover, complex 1 (10 mol %) was able to catalyze the reduction of CO2 under air and/or in wet C6D6 to afford 2a and 2c, but the yield of 2a decreased (Table S2). It is because HBpin decomposed in these reaction conditions to give 2c, and hence the yield of the latter increased. When the amount of complex 1 decreased (5 mol %), the catalytic hydroboration was incomplete (90% conversion, Table S1) in 0.5 h, but the selectivity was still observed. It is noteworthy that complex 1 is the first nonmetal catalytic system that selectively delivers the primarily reduced formoxyborane 2a. Complex 1 is one of the very few examples that catalyze the selective reduction of CO2, including the main-group and transition metal catalysts, namely, an amine-lithium borohydride [(L)Li][HBPh3] (L =N(CH2CH2NMe2)3, TOF = 10 h−1),11 a NHC-copper [IArCu(OtBu)] (yield: 85%, TOF = 0.35 h−1),12 and a PSiPpincer-palladium complex [{PhPSiP}PdOTf] [PhPSiP = Si-(Me)(2-PPh2-C6H4)2] (yield: 93%, TOF = 1550 h−1).13
Moreover, 1 exceeds the base-metal catalysts, [(L)Li][HBPh3] and [IArCu(OtBu)], in terms of both reaction time and TOF. Furthermore, the TOF of the hydroboration of CO2 with HBpin far surpasses the TOF values of the activated nontransition-metal catalysts (TOF = 0.07−2.5 h−1) and even the nonmetal catalysts (TOF = 0.40−14.5 h−1).14
When more potent [BH3·SMe2] was used instead of HBpin, 10 mol % of complex 1 catalyzed the reduction of CO2 with>99% conversion to form a mixture of the borate esters [B(OMe)3] (2d) and [BO(OMe)]3 (2e) in a ratio of 1:4 in 0.5 h (TOF = 19.8 h−1, Scheme 1, Table S3), but selectivity cannot be achieved.
On the other hand, the 1-catalyzed reduction of CO2 with catecholborane (HBcat) slowly proceeded (24 h, >99% conversion, TOF = 0.34 h−1, Table S4) to afford a mixture of diborate ether [(catB)2O] (major product, yield: 70%) and methoxyborane [catBOMe] (minor product, yield: 12%). In comparison with other examples, the above-mentioned NHCcopper complex [IArCu(OtBu)] did not catalyze the selective
reduction of CO2 with HBcat,12 whereas the (amido)-(hydrido)stannylene [Ar*(iPr3Si)NSnH] outperformed 1 using HBcat to nonselectively reduce CO2 into [(catB)OMe] and [(catB)2O] (TOF = 1188 h−1, yield of each compound was not reported).
Upon completing the catalytic hydroboration of CO2 with HBpin, a weak singlet at ca. δ 0.9 ppm, in addition to the signal of 2a, was observed in 11B (Figure S12b) and 11B{1 H} NMR spectroscopy. These indicate that a new boron compound, which does not have any H atom on the boron atom, was formed in the catalysis. To clarify these phenomena, complex 1 was treated with excess HBpin in C6D6 at 60 °C for 5 min, whereby the same 11B NMR signal at δ 0.92 ppm (singlet) was observed, indicating formation of the new boron compound.
The reaction was further analyzed by 1 H and 29Si NMR spectroscopy. The 1 H NMR spectrum shows a set of signals due to methyl protons of IMe and Bpin. The 29Si NMR spectrum displays a singlet at δ −93.0 ppm (29Si{1 H} NMR: δ−95.6 ppm, singlet; Figures S4 and S5), which is an intermediate value between that of 1 (δ −77.9 ppm, 1 JSi−H =283 Hz) and the NHC-hydridosilylene complex [IMe−:SiH-
(SitBu3)] (δ −137.8 ppm).10,15 The upfield Si NMR signal corresponds to a SiII cationic center, and there is no hydrogen atom on the Si center. On the basis of NMR spectroscopic data, the new boron compound formed in the reaction is an NHC-borylsilyliumylidene complex [(IMe)2SiBpin]I (3,Scheme 2). Its composition is also supported by the theoretical 29Si NMR value (δ −94.0 ppm, B3LYP/6-311++G(2df,2pd)//B3LYP/6-31G**, Table S12) and HRMS. After workup, complex 3 was isolated as a colorless solid (yield: ca. 30% for 5 min reaction time). Compound 3 is highly unstable in solution, and hence obtaining suitable single crystals for X-ray crystallography is still in progress. In this context, its structure was simulated by density functional theory (DFT) calculations (Figure S89). Complex 3 easily decomposed in toluene and ethereal solvents to form a white insoluble precipitate, which comprises a mixture of an NHC-boronium cation [(IMe)2Bpin] I (11B NMR: δ 2.37 ppm), an imidazolium salt [IMe−H]I (see Figure S88), and unidentified products. However, they are inactive in any catalytic hydroboration.
In supporting complex 3 that is involved in the catalysis, it was used to catalyze the hydroboration of carbon dioxide with HBpin, whereby selective reduction of CO2 was achieved to obtain 2a (2.5 mol %; time: 0.17 h, yield: 94%, TOF = 227 h−1, Table S1).
These results brought up a question of whether complex 1 or 3 is a genuine catalyst in the hydroboration of CO2. Considering that the conversion of complex 1 into complex 3 is slight (see above), it is suggested that complex 1 could prefer to react with CO2 instead of HBpin in the first step of the catalysis. To gain insight, complex 1 was used to react with CO2 in C5D5N at −40 °C, whereby the 29Si NMR signal (−68.9 ppm, 1 JSi−H = 202 Hz, −40 °C, Figure S10) is downfield shifted in comparison with that of 1, indicating that the Si lone pair electrons interact with CO2 to form Int01 (Scheme 3). The Si−H coupling constant, as well as the absence of signal for the formate, −C(O)H, moiety in the 1 H NMR spectrum, indicates that CO2 did not insert into the Si−H bond in 1 during the catalysis.19a When a stoichiometric amount of HBpin was subsequently added to the reaction mixture, compound 2a was afforded, along with regeneration of complex 1. Notably, the reaction of complex 1 and CO2 was
found to be reversible upon the removal of CO2 and volatiles of the reaction mixture in vacuo at room temperature. As a result, complex 1 does not resemble the (amido)(hydrido)-germylene and -stannylene to catalyze hydroboration through the σ-E−H bond metathesis mechanism (E = Ge, Sn).2,3 DFT calculations were then performed (Scheme 3). It was found that complex 1 is capable of mediating the catalysis, whereby the Si lone pair electrons interact with CO2 to form Int01 (ΔG = −3.1 kcal/mol). The HOMO−3 of Int01 shows that the Si lone pair orbital interacts with the π* orbital of CO2 (Figure S91). Accordingly, the NBO analysis shows that the Si−CCO2 bond results from the overlap of an sp2.14 hybrid on Si with an sp2.59 hybrid on C (Table S13). In the formation of Int01, the natural charge of the Si atom increases from 0.44 (compound 1) to 1.02 (Int01), while that of the CCO2 atom decreases from 1.03 (1) to 0.54 (Int01). Subsequently, the H−B bond of HBpin inserts into the CO bond via a low kinetic barrier (TS01; ΔGInt01→TS01 = 10.6 kcal/mol at 24 °C, Scheme S2), which results in the formation of the formoxyborane 2a and regeneration of 1 (ΔG = −8.5 kcal/mol). In other words, the Si lone pair of electrons in complex 1 is Lewis basic enough to activate CO2 for subsequent hydroboration, whereas the Si−H bond is not sufficiently hydridic to activate CO2. The mechanism is in contrast to the σ-E−H bond metathesis mechanism (E = main-group element) in main-group-elementcatalyzed hydroboration.14c Moreover, the interaction of the Si lone pair in 1 with 2a is endergonic (ΔG = 7.0 kcal/mol, Scheme S5), whereas that with CO2 is exergonic (Scheme 3).
This suggests that complex 1 does not prefer to further react with 2a after a catalytic cycle, while it chooses to react with CO2 again and achieves the selective reduction. DFT calculations also support that the catalytic hydroboration of CO2 via complex 3 is feasible (ΔG = −1.1 kcal/mol; M06-2X/def2-TZVP, Scheme 4, Scheme S1); especially complex 3 catalyzes the hydroboration of CO2 via a lower kinetic barrier (ΔG3→TS04 = 5.0 kcal/mol) in comparison with the mechanism via TS01. It is consistent with experimental results that the activity of 3 in terms of TOF is much higher than that of 1 (Table S1).
However, the kinetic barrier for the formation of 3 is relatively high (ΔG1→3 = 15.2 kcal/mol), which suggests that the mechanism via TS01 should be more dominant than that via 3 and TS04 in the catalysis. Inoue et al. reported that the NHC-arylsilyliumylidene cation [RSi(IMe)2]Cl with sterically hindered substituent 2,6-Mes2C6H3 (R = ArMes) reacted with CO2 at room temperature to afford the NHC arylsilaacylium [RSi(O)(IMe)2]Cl.6 In contrast, when the ArMes substituent was replaced by a lesser sterically hindered substituent, 2,4,6-iPr3C6H2 (R = Tipp), only insoluble amorphous precipitates were formed in the reaction at room temperature. Considering the steric environment of complex 1 and the catalytic conditions, it is anticipated that the 1-catalyzed reduction of CO2 with HBpin via an NHC-parent silaacylium intermediate is not possible. To support this hypothesis, the reaction of 1 with CO2 was studied by DFT calculations. The kinetic barrier and free energy for the formation of an NHC-parent silaacylium intermediate [(IMe)2Si(O)H]I (kinetic barrier: ΔG = 13.4 kcal/mol, Scheme S4) are energetically less favorable in comparison with those for the formation of formoxyborane 2a (Scheme 3).
The presence of IMe in complex 1 also brought up a question of whether IMe dissociates from complex 1 and then catalyzes the hydroboration of CO2. As such, 0.1 mol % of IMe, which presumes a small amount of the NHC ligand is dissociated during the catalysis, was used to mediate the reduction of CO2 with HBpin in C6D6 at 90 °C for 0.25 h, resulting in nonselective catalysis (19% conversion, Table S1) to afford a mixture of [pinBOC(O)H] (2a), [pinBOMe] (2b), and [(pinB)2O] (2c). In comparison with the catalytic results mediated by 1, it is suggested that IMe did not dissociate and was not involved in the hydroboration of CO2.
Theoretical studies and experimental results show that complex 1 is the first stable silicon(II) species undergoing catalytically selective hydroboration with CO2. Interestingly, the proposed mechanism is very similar to a recent report of the PNP pincer ligand-iron(II) hydride complex-catalyzed hydroboration of alkynes, whereby the iron(II) hydride complex [LFeH] (L = 2,5-bis(phosphinomethyl)pyrrolide) can convert into the corresponding iron(II) boryl complex [LFeBpin] in the catalysis, along with both complexes being capable of catalyzing the hydroboration.
Following the hydroboration of CO2, the catalytic ability of complex 1 toward hydroboration of carbonyl compounds was further examined. First, there was no reaction between carbonyl compounds with HBpin in C6D6 at room temperature. Second, complex 1 (10 mol %) was found to be capable of catalyzing hydroboration of aromatic aldehyde ArC(O)H (Ar = Ph, 4a, Table 1, Table S5) as well as its derivatives with electron-donating (Ar = MeC6H4 4b, MeOC6H4 4c) and-withdrawing substituents (MeCO2C6H4 4e, FC6H4 4n) at different positions in 10 min, which quantitatively afforded the
corresponding borate esters. In these reactions, the activity of 1 in terms of TOF (17−115.8 h−1) is intermediate between the heavier group 14 element(II) compounds, namely, (amido)-(hydrido)germylene (17−67 h−1) and -stannylene (400−800 h−1).2 Third, >99% yield was achieved for the hydroboration of nonaromatic aldehydes, namely, cyclohexanecarboxaldehyde 4d and 2,2-dimethylpropanal 4k.
Complex 1 is less active in these reactions (TOF = 19.8−115.8 h−1) in comparison with those catalyzed by the (amido)(hydrido)germylene and -stannylene (TOF = >2000 h−1).2 Fourth, the olefinic functionality in 3-cyclohexene-1-carboxaldehyde 4h, cinnamaldehyde 4m, and 2-methyl-3-phenylprop-2-enal 4q remains intact in the catalyses, showing that the chemoselective hydroboration of aldehydes is possible. Such selectivity is also observed in the hydroboration of thiophene-2-carbaldehyde 4f, ferrocenecarboxaldehyde 4g, furan-2-carbaldehyde 4l, 4-formylbenzonitrile 4r, and isoquinoline-5-carboxaldehyde 4s, in which the functional groups such as nitrile and pyridine were not hydroborated. Such chemoselective catalyses have not been reported before for heavier group 14 element(II) compounds.2 In addition, excellent chemoselectivity of aldehydes over ketones was observed in the catalytic hydroboration of 4-acetylbenzaldehyde 4t. Fifth, as expected, a higher reaction temperature (90 °C) and longer reaction time were required for the chemoselective hydroboration of ketones when compared to aldehydes due to their steric nature (Table 2, Table S6). Various functional groups in aromatic and aliphatic ketones were well tolerated in these reactions, and the corresponding borate esters were afforded in high yields.
The catalytic ability of complex 1 toward the hydroboration of pyridine derivatives was also studied (Table 3, Table S7). First, there was no hydroboration reaction between HBpin and pyridine derivatives in C6D6 at 90 °C. Second, 10 mol % of 1 catalyzed the reaction of pyridine 8a with one equivalent of HBpin in C6D6 at 90 °C to quantitatively form N-boryl-1,4-dihydropyridine 9a as the only regioisomer (TOF = 2.48 h−1), whereas the 1,2-hydroborated product was not formed. Such regioselectivity is comparable with metal-free [MeB{2,4,6-(CF3)3C6H2}2] catalyst (yield of 9a: >99%)17 and the 1,3,2 diazaphosphenium triflate catalyst (yield of 9a: 96%).18 In addition, such catalysis has not been reported for heavier group 14 element(II) compounds. Third, both chemo- and regioselectivity were observed in the 1-catalyzed hydroboration of functionalized pyridines 8b,c and ring-fused pyridine 8d.
Third, the scope of substrates can further be extended to 1,2- and 1,3-pyrazines 8e,f. Upon completing the above-mentioned catalysis (Tables1−3), complex 3 was observed (Figures S18−S20, S33a, S43, S45, S47, S49, S53, S65, S79, S81, S83a, and S85a). These indicate that both complexes 1 and 3 are involved in the catalyses. Similar to the case of CO2, it is suggested that the Si lone pair of electrons in complexes 1 and 3 activate the carbonyl compounds, which are then reacted with HBpin to form the corresponding hydroborated products, along with the regeneration of the catalysts.19b,21 In the case of pyridine derivatives, it is proposed that the catalysis proceeds through coordination of 8 with HBpin first,17 which induces nucleophilic attack of complexes 1 and 3 at the para-position of 8 due to lesser steric congestion.20,21 Subsequent dearomatization of 8 results in displacing the hydride from the borane moiety, which then attacks at the para-position to afford 9, along with the regeneration of the catalysts. In supporting complex 3 that is involved in these catalyses, it was used to catalyze the hydroboration of benzaldehyde 4a (Table S8), 1,4-dioxaspiro[4.5]decan-8-one 6d (Table S9), and pyridine 8a (Table S10), whereby complex 3 shows better activity in terms of TOF in comparison with complex 1.
CONCLUSION
The NHC-parent silyliumylidene cation complex 1 is a versatile catalyst to catalyze the metal-free chemo- and regioselective hydroboration of carbon dioxide, carbonyl compounds, and pyridine derivatives with HBpin to form formoxyborane, borate esters, and N-boryl-1,4-dihydropyridine derivatives, respectively. In particular, complex 1 is the first nonmetal catalytic system that efficiently and selectively delivers the primarily reduced formoxyborane. Its activity is better than that of currently available base-metal catalysts used for such reactions. Mechanistic studies show that complex 1 exhibits transition-metal-like catalysis, whereby the silicon(II) center in complex 1 activates the substrates and then mediates the catalytic hydroboration. In addition, complex 1 was slightly converted into the NHC borylsilyliumylidene complex [(IMe)2SiBpin]I (3) in the catalysis, which was also able to mediate the catalytic hydroboration. It seems reasonable that complex 1 will find a range of other catalytic applications (e.g., C−C bond formation, C−H bond functionalization10). We are currently investigating this possibility and will report on our findings in due course. The trapping of reactive intermediates
with various Lewis bases and acids will also be reported in the course of time.
