Remarkably Efficient Catalysts of Amidine Hydroiodides for the Synthesis of Cyclic Carbonates from Carbon Dioxide and Epoxides under Mild Conditions

Abstract Hydroiodides of amidines effectively catalyzed the reaction of CO2 and epoxides under mild conditions such as ordinary pressure and ambient temperature, and the corresponding 5-membered cyclic carbonates were obtained in moderate to high yields.
