Abstract
The monomeric complex [LiCH2SPh(pmdta)] (3; pmdta = N,N,N',N ",N "-pentamet hyldiethylenetriamine), prepared by metalation of PhSCH3 with n-BuLi/pmdta, undergoes in toluene (room temperature, in daylight) extrusion of the meth ylene group with formation of [LiSPh(pmdta)] and CH4. In refluxing toluene this reaction is thermally induced and the dimerizing alpha-elimination of 3 proceeds with formation of [LiSPh(pmdta)] and H2C=CH2.
