Abstract

The trimethylsilylethyl sulfur group present in 2-(trimethylsilyl)ethyl sulfides, sulfones, sulfoxides and in 2-(trimethylsilyl)ethylsulfonamido derivatives has proved its potential in synthesis. Presence of sulfur and silicon on adjacent carbon atoms provides routes for preparing interesting sulfur or non-sulfur, silicon or non-silicon derivatives like thiols, methyl disulfides, thioesters, thiocyanates, unsaturated derivatives and amines through the selective removal of the trimethylsilylethyl or the tri­methylsilyl group.
