摘要

Abstract Unsubstituted or α-and β-C-substituted silylepoxides react stereospecifically with lithium diphenylphosphide, optionally followed by methylation, to give vinylphosphonium iodides or vinylphosphine oxides resulting from α-opening and silyl enol ethers, vinylsilanes or α-hydroxysilanes by β-opening. On the other hand, α, β-or α, α-disilylepoxides afforded β- silyl vinylphosphine oxides or α-silylated silyl enol ethers by α-and β-cleavage, ...
