Abstract
Phenylthio substituted oligosilanes are obtained from the reaction of oligomeric silicon halides with alkali metal thiophenolates M(I)SPh (M (I) = Li, Na, K). Si-Si bonds are formed when phenylthiooligosilanes a re reacted with alkali metal silicon compounds. Alkali metal thiopheno lates, the second reaction products can be separated easily. Quite sim ilarly, Fe-Si-bonds are obtained from phenylthiosilanes and Na[Fe(CO)( 2)Cp]. In contrast to the related alkali metal halide elimination reac tions of organohalooligosilanes, transmetallations are never observed in the thiophenolate reactions.
