文摘

A series of novel Zn, Cu, Fe supramolecular complexes were designed and synthesized. These supramolecular complexes were proven to be effective catalysts for the coupling reaction of CO2 and epoxides. These catalysts can be easily reused without significant loss of activity and selectivity. Comparison of different two-component dinuclear metal complexes catalysts showed that these complexes were competitive with most catalysts currently available. The mechanism for the reaction was proposed.
