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.
