室温离子液体中二氧化碳与环氧化合物的电催化插入反应

Electrocatalytic Insertion of Carbon Dioxide to Epoxides in Ionic Liquids at Room Temperature

在温和条件下 ,二氧化碳在室温离子液体中可以被电化学活化 .同时 ,活化后的二氧化碳在室温离子液体中与环氧化合物发生插入反应生成环状碳酸酯也得到了较好的结果 .[BMIm][BF4 ]离子液体为反应介质 ,环氧丙烷为反应底物时得到最佳反应结果 .电化学活化对反应的发生是必需的 .

CO2 could be electrochemically activated in ionic liquid at room temperature and readily inserted into epoxides to give the corresponding cyclic carbonates in excellent yields. It was found that [BMhn] [BF4] is the best ionic liquid for the electrochemical synthesis of cyclic carbonates with the highest conversion and selectivity when propylene oxide was taken as the substrate.
