As global warming is getting serious, the concept of sustainable development is attracting increasing interests, and the utilization of CO2 as a renewable resource is receiving intensive study. In the presence of catalysts, CO2 reacts with epoxides to produce cyclic carbonates and polycarbonates. Cyclic carbonates have found wide applications in fields of lithium-ion batteries, organic synthesis and fine chemical production. Polycarbonates are a type of biodegradable polymer material, and can be used as adhesives, food packaging and optical media, etc. The reaction with epoxides is thus one representative of CO2 utilization. Recent studies report that mononuclear and polynuclear metal complexes could catalyze this reaction. Among these examples, heterometallic complexes have shown good activities, due to the synergistic effect between different metals. The synthesis of heterometallic complexes and their applications in catalyzing the reactions of CO2 with epoxides over the past 20 years are reviewed, and the characteristics of various catalysts as well as possible reaction mechanisms are discussed.
