Abstract
The reaction of [(2-N,N-dimethylaminomethyl)phenyl]methylvinylchlorsilane w ith r-BuLi in hexane solvent gave dimers, five isomeric 1,3-disilacyclobuta nes which were separated and characterized. In trapping experiments with va rious 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 intramolec ular donor atom rather than the silene.
