Abstract Diphenylallylvinylsilane undergoes selective addition of n-butyllithium/TMEDA complex on the α-silyl double bond, while methyllithium/TMEDA affords the metallation of the allylic group, without modification of the vinyl group. From our results, metallation appeared highly selective. There is no formation of the dianion. These α-silylcarbanions are good precursors to linear or substituted silylalcohols.
