Description

Other Notes

Treating this chlorosilane with sec-BuLi gives 1-chloro-1-trimethylsilylethyl lithium which reacts with aldehydes and ketones to form methyl ketones via an intermediate α,β-epoxysilane.; Used in an efficient synthesis of R(+)-frontalin; The Grignard reagent is useful for many reactions
