摘要
Ionic liquid mediated ZnBr2 system could catalyze the chemical fixation of CO2 with epoxides with a high selectivity（>98%） and TOF（5 580 h -1） under mild reaction conditions and the catalyst could be reused five times almost without losing its catalytic activity and selectivity. Besides, the pure cis-cyclic carbonate of cyclohexene oxide was obtained over this catalyst system.
