【 摘 要 】

The reaction of [(2-N,N-dimethylaminomethyl)phenyl]methylvinylchlorosilane with t-BuLi in hexane solvent gave dimers, five isomeric 1,3-disilacyclobutanes which were separated and characterized. In trapping experiments with various trapping agents, no corresponding silene-trapping adduct was observed. We suggest that more important species for the formation of five isomeric dimers might be the zwitterionic species generated by virtue of intramolecular donor atom rather than the silene.
