The Uses of CHLORODIMETHYLVINYLSILANE

Chlorodimethylvinylsilane is used to prepare silicon-containing polymers, silaheterocycles and new chelating ligands.

The Uses of CHLORODIMETHYLVINYLSILANE

Metallacycloalkanones have been prepared by the cyclic hydroboration of dialkenyl silanes. In order to obtain one such dialkenyl silane, chlorodimethylvinylsilane was allylated with allyl magnesium bromide (eq 4).The dialkenyl silane was then hydroborated sequentially with thexylborane, followed by treatment with potassium cyanide, trifluoroacetic anhydride, and finally hydrogen peroxide in sodium hydroxide to produce the silacycloheptanone (eq 4).Cyclic silylketones were then further reacted to form acyclic compounds with chiral centers that are difficult to introduce without the use of the silicon tether.

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.
