Bis(phenylthio)methane and [1,3]-dithiane were efficiently deprotonate
d by the NaNH2-Et(OCH2CH2)(2)-ONa complex base. A marked behaviour dif
ference was observed between the sodium carbanion of [1,3]-dithiane an
d the corresponding lithio-derivative; A ''radicaioid'' mechanism is p
roposed to explain the results observed. Copyright (C) 1996 Elsevier S
