摘要
Alkene hydrosilylation catalyzed by Ru(PPh3)3CI(2) in ionic liquids/organic solvents and Rh(PPh3)(3)Cl in ionic liquids was studied in this paper. Both catalytic activity and selectivity of Ru(PPh3)3CI2 were improved in ionic liquid BMImPF(6)/DME medium. The conversion of hexene and selectivity of,8-adduct for the hydrosilylation reaction of 1-hexene with triethoxysilane catalyzed-by Ru(PPh3)(3)Cl-2 in ionic liquid BMImPF(6)/DME (WV= 1/4) medium at 90 degrees C were 100% and 89.0%, respectively. While the conversion of hexene and selectivity to beta-adduct catalyzed by Rh(PPh3)(3)Cl in sole BMIMPF6 at 90 degrees C were 100% and 99.9%, respectively. The Rh(PPh3)(3)Cl in BMImPF(6) catalyst system could be recovered easily and be reused more than three times without noticeable loss of its catalytic activity and selectivity.
