A series of rare earth metal complexes RE(TPP)(acac) (RE = Nd^III, Yb^III, Eu^III, Er^III, Pr^III, and Lu^III; TPP = 5,10,15,20‐tetraphenylporphyrin) were synthesized and characterized via UV–vis, IR, and elemental analyses. Their catalytic activities on the synthesis of cyclic carbonates from carbon dioxide and epoxides under different reaction conditions (temperature, pressure, and reaction time) were investigated. Catalytic reaction tests showed that the complex Lu(TPP)(acac) could significantly enhance the catalytic reactivity under mild conditions without any co‐solvent.

稀土-卟啉配合物催化剂，可在温和条件下将二氧化碳转化为环状碳酸酯

合成了一系列稀土金属配合物RE（TPP）（acac）（RE = Nd ^III，Yb ^III，Eu ^III，Er ^III，Pr ^III和Lu ^III ; TPP = 5,10,15,20-四苯基卟啉）并通过UV-vis，IR和元素分析进行表征。研究了它们在不同反应条件（温度，压力和反应时间）下对由二氧化碳和环氧化物合成环状碳酸酯的催化活性。催化反应测试表明，复杂的Lu（TPP）（acac）可以在温和条件下显着提高催化反应活性，而无需任何助溶剂。
