New Stereoselective Synthesis of (Z)-α-Iodovinylsilanes via One-Pot Iododesilylation/Isomerization of 1,1-Bis(silyl)alk-1-enes

Abstract

Synthetically useful (Z)-2-aryl-1-iodo-1-silylethenes were prepared in good to excellent yields via one-pot monoiodo­desilylation/isomerization of readily accessible 2-aryl-1,1-bis(silyl)ethenes using N-iodosuccinimide or bis(pyridine)iodonium tetrafluoroborate under mild conditions.

Key words

halogenation - iododesilylation - vinylsilanes - organometallic reagents - stereoselective synthesis
