The facile thermal elimination of LiOR (R = Me, Ph) in the reaction of [o-(N,N-Dimethylaminomethyl)phenyl]-organoxymethylvinylsilane with t-BuLi was discussed. It was found that the intramolecular coordination by the amino group enhanced the thermolability of α-lithiated organoxysilane. The analysis suggested the an intramolecular donor atom results in formation of a charge-separated zwitterionic species.
