摘要

Abstract Pure cis-vinylsilanes are efficiently converted to cis-epoxysilanes which react smoothly with Li 2 Cu (CN)(CH 2 TMS) 2 to provide the corresponding erythro disilylated alcohol, in excellent yield and isomeric purity. Elimination of the elements of TMSOH affords either the pure cis-or trans-γ-substituted allylsilanes, under basic or acidic conditions, respectively.
