摘要

Benzylmethylchlorosilanes were prepared in high yields by the dechlorinative silylation of benzylic chlorides with methylchlorodisilanes MenSi2Cl6-n (n = 2, 3, and 4) in the presence of a catalytic amount of Pd(PPh3)4. ... The Si-Si cleavage reaction of disilanes with organic halides, formally a dehalogenative silylation, constitutes a silicon-carbon bond forming process of quite a new type (eqn. 1). This reaction provides a facile route to functional silicon compounds which ...
