First Direct Deprotonation−Electrophile Trapping of Simple Epoxides: Synthesis of α,β-Epoxysilanes from Terminal Epoxides

Abstract

[figure: see text] The presence of a suitable diamine ligand is the key to achieving ring lithlation-substitution of epoxides without the need for activating substituents on the epoxide and constitutes a new synthetic entry to trans-alpha,beta-epoxysilanes.
