Dual-ionic liquid system: an efficient catalyst for chemical fixation of CO₂ to cyclic carbonates under mild conditions

Abstract

An easily prepared novel dual-ionic liquid system can catalyze the reactions of CO₂ and epoxides to form cyclic carbonates under mild conditions (1 atmos CO₂, <italic>T</italic> = 30–60 °C) with excellent yields in the absence of any solvents or additives.
