[Uses]

(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.
  • 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.
  • 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.
  • In the palladium-catalyzed asymmetric silaboration of allenes and alkanes to offered corresponding β-borylallylsilanes and 2-boryl-1-silylalkanes respectively.

[Uses]

2-(Dimethylphenylsilyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane is widely used as silaboration and silylation reagent for unsaturated organic compounds; a derivative having diethylamino group on the silicon atom for use as a precursor for silylene generation.
[Preparation]

2-(Dimethylphenylsilyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (1) is prepared by reaction of dimethylphenylsilyllithium with 4,4,5,5-tetramethyl-1,3,2-dioxaborolane (pinacolborane, 2 equiv) or 2-isopropoxy-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (2 equiv).
