Hydrosilylation catalysed by a rhodium complex in a supercritical CO2/ionic liquid system

Abstract

The hydrosilylation of alkenes in a supercritical CO2 (scCO2)/ionic liquid (IL) system was investigated. Rh(PPh3)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.
