摘要： 研究了钌卟啉络合物催化二氧化碳与环氧化合物的偶联反应,考察了不同钌卟啉络合物、助催化剂、反应温度、催化剂用量及不同共催化剂对二氧化碳与环氧化合物偶联反应的影响. 结果表明,当以Ru(TPP)(PPh3)2为催化剂,重氮乙酸乙酯为助催化剂,苯基三甲基三溴化铵为共催化剂,且底物∶催化剂∶助催化剂∶共催化剂摩尔比为200∶1∶1∶2, 反应温度为323 K时,不同环氧化合物都取得了较高的环碳酸酯产率.

Abstract: The coupling reaction of epoxides with carbon dioxide catalyzed by ruthenium porphyrin was studied. Reaction conditions were optimized. The new catalyst system of Ru(TPP)(PPh3)2/phenyltrimethylammonium tribromide (PTAT) promoted by ethyl diazoacetate (EDA) is very efficient to catalyze the coupling reaction of rious epoxides and CO2 at 323 K and the molar ratio of substrate∶catalyst∶EDA∶PTAT=200∶1∶1∶2.
