One direct and efficient procedure for the synthesis of 1,1-disilylated terminal alkenes is demonstrated in this paper. To overcome and rationally utilize the steric hindrance of silyl units, the cationic ruthenium catalyst [CpRu(MeCN)3]+ was found to be effective for Markovnikov hydrosilylation of 1-silyl terminal alkynes with high yields and excellent regioselectivity. Dissimilarities between alkyl and alkoxy silyl units lead to versatile product derivatizations toward a variety of useful building blocks.

Nucleophilic substitution reactions of chlorosilanes with aryl Grignard reagents take place efficiently in the presence of copper(I) iodide to afford tetraorganosilanes.

(Chemical Equation Presented) The silver savior: Nucleophilic substitution reactions of chlorosilanes with aryl Grignard reagents have been developed which take place under silver catalysis to afford tetraorganosilanes (see scheme). This transformation is likely to be promoted by diarylargentate reagents that are generated in situ.

A new convenient and effective method for the synthesis of unsymmetrical 1,1-bis(silyl)ethenes is described. The synthetic methodology involves selective silylative coupling cyclization of N-methyl-N-(dimethylvinylsilyl)-2- (dimethylvinylsilyloxy)ethanamine catalyzed by a ruthenium hydride complex and subsequent one-pot reaction of the cyclic bis(silyl)derivative with Grignard reagents followed by alcoholysis. As a result, a variety of 1,1-bis(silyl) ethenes containing different substituents at the silicon atoms were produced in regiocontrolled manner with considerably high efficiency.

Insertion of Vinylsilane into the Ruthenium-Silicon-Bond - Direct Evidence for the Non-metallacarbene Mechanism of Silylalkene Disproportionation
Marciniec, Bogdan,Pietraszuk, Cezary
, p. 2003 - 2004 (2007/10/02)
The reversible insertion of the vinylsilane molecule into the Ru-Si bond occurs in two different ways to give E-1,2-bis(silyl)ethene and 1,1-bis(silyl)ethene which, in combination with the previous experiments by Wakatsuki et al., provides convincing evidence for a non-metallacarbene mechanism of silylalkene disproportionation.
