Abstract

Summary The synthesis of 1R, 1R′, 2, 3, 4, 5-tetraphenyl-1-silacyclopentadienes I–V, VII, X, XII and XIII is described. 1-Chloro-1-silacyclopentadiene VI reacts with lithium/ trimethylchlorosilane to the silylated compound VII and with lithium alone to the disilane VIII. The silacyclopentadiene IX with an Si− H bond reacts with n-butyllithium under substitution at silicon and by further 1, 4-addition of lithium hydride, the hydrolysis products XVa, XVb ...
