Application
(Dimethylphenylsilyl)boronic acid pinacol ester (Suginome′s reagent) can be used as a reagent:
- For the selective addition of dimethylphenylsilanyl group to cyclic and acyclic unsaturated ketones, esters, acrylonitriles using a copper catalyst.[1]
- In the synthesis of (Z)-4-boryl-1-silyl-2-alkene derivatives by stereoselective addition of silicon-boron bond to acyclic 1,3-dienes in presence of Ni catalyst.[2]
- In the preparation of silyl-substituted butenoate and β-silyl-substituted acrylate derivatives from allenes and propiolate derivatives via hydrosilylation reactions using a copper catalyst.[3]
- In the palladium-catalyzed asymmetric silaboration of allenes and alkanes to offered corresponding β-borylallylsilanes and 2-boryl-1-silylalkanes respectively.[4][5]

An efficient and general copper(I)-catalyzed method for the synthesis of multi-substituted vinylsilanes is reported. Multi-substituted allenes with electron-withdrawing groups and propiolate derivatives reacted well with (dimethylphenylsilyl)boronic acid pinacol ester to afford silyl-substituted butenoate derivatives and β-silyl-substituted acrylate derivatives, respectively.
