Abstract

Bis (phenylthio) methane and [1, 3]-dithiane were efficiently deprotonated by the NaNH2-Et (OCH2CH2) 2-ONa complex base. A marked behaviour difference was observed between the sodium carbanion of [1, 3]-dithiane and the corresponding lithio-derivative. A “radicaloid” mechanism is proposed to explain the results observed.
