Abstract

Tris(trimethylsilyl)methyllithium (TsiLi) reacts with CS2 via cleavage of the C=S double bond and unexpected rearrangement to give sulfur-containing organosilicon compounds. The intermediate, from the reaction between TsiLi and CS2 is not stable but it has been trapped by various alkyl halides to give mercaptobis-(trimethylsilyl)-thiones. These reactions are quantitative and high yields in short periods of time have been obtained.
