Abstract

Abstract Vinylsilanes and/or allylsilanes are formed upon silylation of terminal alkenes with R 3′ SiCl in the presence of a Grignard reagent and a catalytic amount of [Cp 2 ZrCl 2][Eq.(a)]. The reaction also proceeds under mild conditions when silylsulfides (X= SPh), silylselenides (X= SePh), and silyltellurides (X= TePh) are used in place of chlorosilanes (X= Cl). R ″= alkyl, aryl, alkylsilyl; R′= Me, Et, nPr; R= CH 2 R ″, aryl, H.
