Uses
Different sources of media describe the Uses of 1719-58-0 differently. You can refer to the following data:
1. Chlorodimethylvinylsilane is used to prepare silicon-containing polymers, silaheterocycles and new chelating ligands.
2. 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.
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.
Flammability and Explosibility
Highlyflammable
Check Digit Verification of cas no
The CAS Registry Mumber 1719-58-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,1 and 9 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1719-58:
(6*1)+(5*7)+(4*1)+(3*9)+(2*5)+(1*8)=90
90 % 10 = 0
So 1719-58-0 is a valid CAS Registry Number.

Paragraph 0039; 0040, (2019/02/19)
The invention belongs to the technical field of organic synthesis, and particularly relates to a synthesis method for dimethylvinylchlorosilane. Antimony butter SbCl3 is taken as a catalyst, dimethyldichlorosilance Me2SiCl2 is taken as a raw material, and the antimony butter SbCl3 and the dimethyldichlorosilance Me2SiCl2 react with vinylmagnesium bromide or vinylmagnesium chloride to undergo Grignard reaction; the antimony butter SbCl3 which performs a key function as the catalyst is added to enable the yield of the dimethyldichlorosilance Me2ViSiCl to be greatly improved to be 80% or more (91% is highest) from the yield which does not exceed 15% according to the report in an original literature; when the comparison reaction of the catalyst antimony butter SbCl3 is not used, the yield of the dimethylvinylchlorosilane Me2ViSiCl is only 32.8%.
