Uses
Chlorodimethylvinylsilane is used to prepare silicon-containing polymers, silaheterocycles and new chelating ligands.
Uses
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, C
4H
9ClSi) 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.
Flammability and Explosibility
Highly flammable
