Reactions of 〔(2-N, N-Dimethylaminomethyl)phenyl〕methylvinychlorosilane with t-BuLi: Synthesis and Characterization of Five Isomeric 1,3-Disilacyclobutanes.


Abstract

The reaction of [(2-N,N-dimethylaminomethyl) pheny] methylvinychlorosiane with t-BuLi in hexane solvent gave dimers, five isomeric 1,3-disilacyslobutanes which were weparated and charaterized. In trapping experiments with various trapping agents, no corresponding silene-trapping aduct 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.
