The hydrosilylation of alkenes in a supercritical CO2 (scCO 2)/ionic liquid (IL) system was investigated. Rh(PPh 3)3Cl exhibited excellent catalytic activity and selectivity. KOtBu was used as an additive, and no hydrogenation by-product (alkane) was detected in the scCO2/IL system. During hydrosilylation in the scCO2/IL system, the reactants were possibly transferred into the IL phase by scCO2, in which the catalyst was dissolved. The products can be flushed with scCO2 after the reaction and the catalyst/IL system reused.

A graphite oxide-supported Karstedt heterogeneous catalyst was synthesized from vinyltriethoxysilane via immobilization on graphite oxide, followed by reacting with chloroplatinic acid. The samples were characterized by FT-IR, TGA, ICP-AES, XRD and TEM te

Rhodium complexes bearing N-heterocyclic carbene (NHC) ligands were prepared from bis(η4-1,5-cyclooctadiene) dichlorodirhodium and 1-alkyl-3-methylimidazolium-2-carboxylate, and the catalytic properties of rhodium complexes prepared in the hydrosilylation of alkenes in ionic liquid media were investigated. It was found that both the catalytic activity and selectivity of the rhodium complexes bearing NHC ligands were influenced by the attached substituents of the imidazolium cation. Additionally, rhodium complexes bearing NHC ligands in ionic liquid BMimPF6 could be reused without noticeable loss of catalytic activity and selectivity.
