A series of novel monothiolate-bridged dirhodium complexes, [Cp Rh(μ-SR)(μ-Cl)2RhCp ][BF4] {Cp? = ??5-C5Me5, R = tertiary butyl (tBu), 1a; R = ferrocenyl (Fc), 1b; R = adamantyl (Ad), 1c} were designed and successfully synthesized, which can smoothly facilitate highly regioselective and stereoselective hydrosilylation of terminal alkynes to afford β(Z) vinylsilanes with good functional group compatibility. Furthermore, the hydride bridged dirhodium complex [Cp Rh(μ-StBu)(μ-Cl)(μ-H)RhCp ][BF4] (5) as a potential intermediate was obtained by the reaction of 1a with excess HSiEt3.

The heterogeneous hydrosilylation of alkynes catalysed by platinum on titania is reported. A variety of hydrosilanes react with both terminal and internal alkynes to furnish the corresponding vinyl silanes in high yields and short reaction times as well as in a regio- and stereoselective manner. The catalyst can be easily recovered and reused in several consecutive cycles.

The effect of substituents at silicon on the cross-metathesis of trisubstituted vinylsilanes with olefins

Efficient cross-metathesis of vinylsilanes, carrying a large spectrum of different substituents at silicon, with various olefins in the presence of the first and second generation Grubbs catalyst and Hoveyda-Grubbs catalyst is described. On the basis of the results of equimolar reactions of vinylsilanes with ruthenium alkylidene complexes and experiments with deuterium-labelled reagents, a general, metallacarbene mechanism for the cross-metathesis of trisubstituted vinylsilanes with olefins has been suggested. Reaction was proved to be a valuable method for synthesis of unsaturated organosilicon derivatives.

Cross-coupling reaction of pentacoordinate alkenylsilicates with organic halides and triflates catalyzed by a palladium complex

Isolated pentacoordinate alkoxy-substituted alkenylsilicates, are readily prepared by mixing alkenyltrialkoxysilane, catechol and triethylamine at room temperature.Cross-coupling reactions of these alkenylsilicates with organic halides or triflates are catalyzed by a palladium complex and proceed very smoothly and cleanly to give the corresponding alkenes.The cross-coupling reactions could be also attained by a one pot operation without isolation of pentacoordinate organosilicates.The mechanism of this cross-coupling reaction is also described here. alkoxy-substituted alkenylsilicate / pentacoordinate silicate / cross-coupling / palladium catalyst / aryl halide / aryl triflate / styrene derivative / 1,3-diene

The β-Effect: Changing the Ligands on Silicon

The ability of a silyl group to stabilize a carbocation β to silicon, the β-effect, is directly related to the electron-withdrawing ability of the groups on silicon.This was shown by using the degree of syn addition of bromine to (E)-β-silylstyrenes as a
