Rh-catalyzed anti-Markovnikov hydrosilylation of terminal alkenes and tertiary silanes using readily-available PPh3 as the ligand was reported. This method facilitated the effective synthesis of alkylsilanes with a wide substrate scope and high

Alkene hydrosilylation and dehydrogenative silylation reactions, mediated by [Rh(cod)(NHC)(OH)] complexes (cod = 1,5-cyclooctadiene; NHC = N-heterocyclic carbene) are described. The study details a comparison of the catalytic activity and steric characteristics of four rhodium complexes bearing different NHC ligands. The novel [Rh(cod)(Ii-PrMe)(OH)] complex (Ii-PrMe = 1,3-diisopropyl-4,5-dimethylimidazol-2-ylidine) was designed to improve the reactivity of Rh(i)-hydroxides and proved to be a successful promoter of hydrosilylation and dehydrogenative silylation, displaying good stereo- and regiocontrol.

(Chemical Equation Presented) The Grubbs second generation ruthenium catalyst was shown to catalyze various olefin ring closing metathesis and hydrosilylation reactions in aqueous medium. Reactions proceeded in pure water without any additives or cosolvents, in a short period of time. We found that inhomogeneity of the reaction mixture does not prevent high conversion (70-95%) of the products in both reactions.
Homogeneous catalytic hydrosilylation of the C=C double bond with platinum catalysts

Hydrosilylation of vinyl- and vinylidene-type olefins (styrene (1a), 2-phenyl-propene (1b), methyl methacrylate (6)) has been carried out with either PtCl2 (dissolved in the substrate) or a platinum-phosphine catalyst prepared in situ.The activity and regioselectivity of the platinum-phosphine catalysts depend strongly on the phosphine structure and the metal/ligand ratio.Complexes involving chelating phosphines are inactive.Although mainly linear regioisomers are formed (2 and 7 respectively) in the reaction of 6, some 1,4-addition of the silane to the conjugated system also takes place to give a silyl ketene acetal derivative (8).A marked decrease in the reaction rate is observed if Ph3SiH instead of Et3SiH is used as the hydrosilylating agent.
