Metathesis of silicon-containing olefins. VIII. Synthesis of alkenyl (phenyl, methyl) substituted silanes by olefin metathesis

1-Tri(phenyl, methyl)silyl-1-alkenes of the general formula RCH=CHSiMe3-nPhn (where n = 1-3, R = CmH2m+1, m = 5,6,8,10, and 12; Ph) have been prepared by a novel method, viz. by a very effective cross-metathesis of vinyltri(phenyl, methyl)silanes with 1-alkenes and styrene catalyzed by ruthenium and rhodium complexes.A tenfold excess of 1-alkene in the reaction mixture gave stereospecific 1-tri(phenyl, methyl)silyl-1-alkenes (predominantly E-isomers) in high yields of up to 90percent (in turn of vinylsilane).The products were identified by spectroscopic (IR, Raman, 1H, 13C NMR and GC-MS) methods.

Copper-Photocatalyzed Hydrosilylation of Alkynes and Alkenes under Continuous Flow

Herein, the photocatalytic hydrosilylation of alkynes and alkenes under continuous flow conditions is described. By using 0.2 mol % of the developed [Cu(dmp)(XantphosTEPD)]PF6 under blue LEDs irradiation, a large panel of alkenes and alkynes was hydrosilylated in good to excellent yields with a large functional group tolerance. The mechanism of the reaction was studied, and a plausible scenario was suggested.

Reaction of hydrosilanes with alkynes catalyzed by gold nanoparticles supported on TiO2

Gold nanoparticles supported on TiO2 (0.8-1.4 mol %) catalyze the β-(E) regioselective hydrosilylation of a variety of functionalized terminal alkynes with alkylhydrosilanes in 1,2-dichloroethane (70 °C). The product yields are excellent, and the reaction times relatively short, while almost equimolar amounts of alkynes and hydrosilanes can be used. Minor side-products in up to 35% relative yield of cis-oxidative (dehydrogenative) disilylation, an unprecedented reaction pathway, are formed in the cases of the less hindered hydrosilanes and alkynes. Triethoxysilane reacts faster and affords apart from β-(E) addition products, minor α-hydrosilylation regio-isomers in upto 15% relative yield. Internal alkynes are generally less reactive or even unreactive. It is proposed that cationic Au(I) species stabilized by the support are the reactive catalytic sites, forming in the presence of hydrosilanes either silyl-Au(III)-H (hydrosilylation pathway) or Au(III)-disilyl species (dehydrogenative disilylation pathway). Regarding the mechanism of hydrosilylation, kinetic experiments are in agreement with silyl carbometallation of the triple bond in the rate determining step of the reaction.
