Silylcupration of allenes and subsequent electrophilic trapping by allylic phosphates. A novel approach to silylated 1,4-diene systems

Abstract

[formula: see text] Silylcupration of allenes with a lower order silylcuprate reagent followed by an electrophilic trapping reaction with allylic diphenyl phosphates has been studied. This reaction provides a new route to 1,4-diene systems having an allylsilane moiety.
