Description

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]
