Deprotonation of Aryl Methanedithioate by Lithium Amides: Formation of Lithium Arylthio(thioxo)methanide Having Unique Reactivity

Abstract

Deprotonation of aryl methanedithioate 5 bearing a bowl-type bulky subsituent with lithium tetramethylpiperidide at low temperature gave organolithium species 9 which was in equilibrium with a dimeric species 10; 9 extruded C=S at higher temperatures, thus representing a new, convenient source of C=S.
