Abstract Bis(pentachlorophenyl)dimethylsilane and 1,3-bis(pentachlorophenyl)tetramethyldisiloxane can be metalated with n-butyllithium in THF at low temperature to give organolithium reagents, in which the lithium atom is in the para -position to the silicon atom. Several compounds were obtained by treating the organolithium reagents thus formed, with chlorotrimethylsilane, 1,3-dichlorotetramethyldisiloxane, dimethyldichlorosilane and dimethylchlorosilane. Some of the organosilicon compounds reported were prepared by two alternative routes to prove further the proposed structures.
