Abstract
Synchronous insertion of alkyl group and deoxygenation reaction were achieved from α,β-epoxy silanes by the treatment with organolithium or organolanthanoid reagents in a regio- and stereoselective manner, i.e., the reaction of (Z)-α,β-epoxy silanes gave the corresponding alkylated (Z)-vinylsilanes, and (E)-α,β-epoxy silanes were transformed into desilylated alkylated (E)-olefins.Keywords
