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

Metallacycloalkanones have been prepared by the cyclic hydroboration of dialkenyl silanes. In order to obtain one such dialkenyl silane, chlorodimethylvinylsilanewas 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.

Highlyflammable
