INTRODUCTION
Arylboronic acids and esters have found a prominent place in the synthetic chemist’s toolbox, the latter being often preferred for convenience in their purification and characterization and for their ability to be observed via gas or liquid chromatography. Despite the recent developments in transition metal-catalyzed borylation,1-4 the cheapest and most common way of synthesizing arylboronic acids and esters remains the reaction of an organolithium or organomagnesium intermediate with a trialkylborate at low temperature, typically -78 C (Li) up to -10 C (Mg).1,5 An attractive method in this context is the generation of the aryl Grignard reagent by metal-halogen exchange using reagents such as i PrMgBr or i PrMgCl 3 LiCl.6 Compared to the historic Grignard synthesis from Mg0, this procedure, introduced by Knochel and Cahiez,7 allows the preparation of the reagent at milder temperatures (-40 C to room temperature), which broadly enlarges the functional group compatibility: for instance,
arylmagnesium halides bearing ester or nitrile substituents become accessible. The exchange reaction is generally completed within hours, and the organomagnesium species can then be reacted with an electrophile at temperatures below 0 C, typically -30 to -10 C in the case of a trialkylborate.
The functionalized Grignard reagents are intrinsically unstable, even if they can be kept for several hours at low temperature.6a Furthermore, with the expanding use of this magnesium-halogen method for the preparation of arylmagnesium reagents, some concerns have been raised regarding the stability of the reaction mixture. Process safety evaluation studies9 revealed that an exothermic decomposition of the solution is possible—even for phenylmagnesium chloride—and that onset temperatures as low as 55 C can be found. The structure of the aromatic ring and the concentration of the solution have a strong influence on the severity of the event, fluorine substituents and concentrated media being detrimental. A solution to avoid the prolonged coexistence of the aryl Grignard reagent, reactive functional
groups, and i PrX, the byproduct of the magnesium-halogen exchange, would be to directly trap the reactive species by the electrophile in situ. Such a procedure has proven efficient in some cases with organolithium species and triisopropyl borate, but yields are still inadequate for challenging substrates such as ethyl p-bromobenzoate.10 Regarding the magnesium-halogen exchange reaction, scarce examples of in situ trapping with trialkylborates can be found, with varying degrees of success.11
Among boronic acid derivatives, arylboronic hexylene glycol esters emerged as interesting compounds. Murata’s team12 and ours13 have shown that they exhibit excellent stability toward air, water, and chromatography,14 and undergo Suzuki-Miyaura reactions with aryl iodides, bromides, and triflates in excellent yields. Advantageously, hexylene glycol—a solvent—is much less expensive than pinacol.15 We thus wondered whether 2-isopropoxy-4,4,6-trimethyl-1,3,2-dioxaborinane16 (MPBOi Pr, 1) could be an efficient in situ trapping agent for arylmagnesium species issuing from a magnesium-halogen exchange.
RESULTS AND DISCUSSION
Reagent 1 was easily prepared from boric acid, hexylene glycol, and isopropanol by azeotropic removal of water (see Experimental Section),17 and methyl 4-iodobenzoate 2a was chosen as the first substrate. The magnesium-iodine exchange reaction was carried out with in situ quench, at 0 C, through gradual addition of a THF solution of i PrMgCl 3 LiCl to the mixture of 1 and 2a in THF (Scheme 1).18
Monitoring the reaction by GC analysis showed that the transformation of 2a into arylboronic ester 3a was complete by the end of the addition. Hydrolysis of the reaction mixture led to a dramatically clean crude product19 and to the corresponding boronic ester in 77% isolated yield after a simple filtration over silica gel. This first result was very promising, given the competitive reactions at stake (Scheme 2): magnesium-iodine exchange, nucleophilic addition of the organomagnesium species onto the electrophilic MPBOi Pr20 or onto the carboxylic ester.6b Once the exchange has occurred, the aryl Grignard reagent does not accumulate but instantaneously reacts with 1 to give the arylboronic ester. Indeed, we did not detect any methyl benzoate by GC analysis of hydrolyzed aliquots sampled during the addition of i PrMgCl 3 LiCl. The selectivity in the case of 2a can be partly explained by the presence of the electron-withdrawing substituent, known to strongly accelerate the magnesium-halogen exchange.21 However, the nature of the halogen is crucial.
Indeed, in the case of aryl bromide 20 a, the exchange proved too slow22 compared to the nucleophilic addition onto 1, and methyl 4-bromobenzoate 20 a was recovered unchanged when submitted
to the protocol from Scheme 1. We then investigated the nature of the aryl iodides that could undergo the magnesium-iodine exchange in the presence of MPBOi Pr 1 (Scheme 3 and Table 1). The reaction proceeds smoothly with aryl iodides bearing electron-withdrawing reactive substituents such as ester and nitrile groups, leading to arylboronic hexylene glycol esters 3a-c in high yields (Table 1, entries 1-3).
The use of i PrMgCl 3 LiCl was not suitable for a nitro group and led to a complex mixture. PhMgCl is known to allow magnesiumiodine exchange in the presence of an o-nitro group, but to react on
a nitro group in meta- or para- position.23 In the present system, the only reaction that takes place is between PhMgCl and MPBOi Pr: a mixture of unreacted 1-iodo-3-nitrobenzene 2d and phenylboronic ester was obtained (Table 1, entry 4).
Starting from diiodobenzenes, the monoborylated products 3e-f are selectively obtained (Table 1, entries 5-6); traces (∼1%) of the diborylated compound were detected only in the case of the para disubstituted 2e, by 1 H NMR and GC analysis of the crude material.24 The borylation of o-halo iodobenzene occurs at the iodine position, and no product resulting from aryne formation25 could be detected (Table 1, entries 6-8).
Running the reaction at lower temperature slightly improved the yield in arylboronic ester 3f (Table 1, entry 6). The o-trifluoromethyl arylboronic ester 3i was prepared in quantitative yield up to a 100 mmol scale using only a slight excess (10 mol %) of reagents (Table 1, entry 9). This excellent result is particularly interesting as the corresponding aryl Grignard reagent is reported to be prone to a highly exothermic decomposition.9b The very clean crude product was engaged without further purification in a Suzuki-Miyaura coupling leading to biaryl 5 bearing electron-withdrawing substituents on both aryl rings in 80% unoptimised yield (Scheme 4).26 2-Pyridyl boronic acids are notoriously unstable, and ester derivatives are therefore attractive compounds;27 we were thus pleased to obtain 6 bromopyridin-2-yl boronic ester 3j in excellent yield (Table 1, entry 10).
Electron-donating substituents proved detrimental to the reaction: the slower rate of the magnesium-iodine exchange28 (constant k1 in Scheme 2) made the nucleophilic addition of the alkylmagnesium species onto 1 competitive. i PrMgCl 3 LiCl was consumed to give MPBi Pr and the conversion of aryl iodide 2 was therefore incomplete; no synthetically useful yield of arylboronic ester 3 could be obtained at 0 C (Table 1, entries 11-13).
As we can see from the above results, the electronic nature of the aryl iodide plays an important part in the outcome of the borylation, by modifying the rate constant k1 in Scheme 2. For a given aryl iodide, other parameters can favor the exchange reaction over the nucleophilic addition, by changing either the rate constants (k1, k2) or the reaction rates. To test the influence of the reaction conditions, we chose 2-iodoanisole as a borderline substrate for which k1 is close to k2; 29 some aryl iodide remained unreacted, and we used the conversion of 2m into arylboronic ester 3m as a measure of effectiveness (Scheme 5 and Table 2).
The conversion reached 25% when conditions from Table 1 were applied (Table 2, entry 1). Running the reaction at lower temperature was again beneficial (Table 2, entry 3). As stressed by Knochel, LiCl accelerates the magnesium-halogen exchange (higher k1);6b we observed in our case that i PrMgCl 3 LiCl significantly improved the conversion of 2m into 3m (compare Table 2, entries 1, 4, and 6).
Decreasing the amount of MPBOi Pr 1 (1.1 equiv vs 1.9 equiv) slows down the rate of the direct addition of i PrMgCl 3 LiCl onto 1. As a result, a better, albeit still low, conversion of the aryl iodide was achieved (compare Table 2, entries 2 vs 1 and 5 vs 4). More generally, decreasing the amount of MPBOi Pr 1 has a practical consequence: crude materials even cleaner than usual are obtained and can be directly engaged in further transformation (Scheme 4).30
Withthe rate constant k2 being directly correlated tothe structure of the trapping agent, we wondered whether our procedure for the preparation of functionalized arylboronic esters could be applied to the corresponding pinacol derivative 2-isopropoxy-4,4,5,5-tetramethyl[1,3,2]dioxaborolane (PinBOi Pr, 6).31 Indeed, pinacol esters are the best-known arylboronic esters for SuzukiMiyaura reactions.1 We chose o-iodo trifluoromethylbenzene 2i and o-iodo anisole 2m as representative substrates (Scheme 6 and Table 3). In the case of the aryl iodide bearing an electronwithdrawing substituent, an excellent 93% yield in the pinacol ester 7i was obtained (Table 3, entry 1). In the borderline case of substrate 2m, PinBOi Pr 6 gave better results than MPBOi Pr 1, whichever alkyl Grignard reagent was used (compare Table 3, entries 3 vs 2 and 5 vs 4). The extent of nucleophilic addition of the isopropylmagnesium species onto 6 is probably lessened by the increased steric hindrance around the boron atom compared to 1. Finally, as seen in Table 2, the effect of the borate ester stoichiometry proved significant (compare Table 3, entries 6 vs 5).
CONCLUSION
Combining the generation, at 0 C, of the aryl Grignard reagent by magnesium-iodine exchange with its in situ trapping by a cyclic borate ester proved to be a very simple, safe, and selective procedure for the preparation, in excellent yields and crude purity, of functionalized arylboronic esters from electrondeficient aryl iodides. Regarding arylboronic hexylene glycol esters, the present procedure is complementary to the Pdcatalyzed borylation of electron-rich aryl halides with 4,4,6-trimethyl-1,3,2-dioxaborinane (methyl pentanediol borane).
