General description

Chloro(dimethyl)vinylsilane (Dimethylvinylchlorosilane, Vinyldimethylchlorosilane, C4H9ClSi) is an organosilicon compound. It participates in the preparation of 1,1,2,2-tetramethyl-1,2-divinyldisilane. It undergoes [2+4] cycloaddition reaction with t-butyllithium in the presence of 2,3-dimethyl-1,3-butadiene to afford cycloadducts.

Application

Chloro(dimethyl)vinylsilane may be used in the synthesis of dimethyl(prop-2-ynyloxy)(vinyl)silane.
Chloro(dimethyl)vinylsilane may be used to prepare silicon-containing polymers, silaheterocycles, and new chelating ligands.
