Abstract

Ionic liquid–modified silica has been prepared by a “one-pot” reaction of activated silica, 3- chloropropyltriethoxysilane, and alkylimidazole or pyridine. It was found that the catalytic activity and β-adduct selectivity of the supported catalyst Rh (PPh3) 3Cl/ionic-liquid– modified-SiO2 for the hydrosilylation reaction of alkenes with triethoxysilane was significantly improved. Furthermore, the catalyst system could be recovered easily.
