Salen-Co(Ⅲ)配合物催化CO2和环氧化合物合成环状碳酸酯的反使用了温室气体CO2为原料来合成有用的分子,同时该反应符合原子经济性,是最有潜力的绿色化学反应之一.讨论了Salen-Co(Ⅲ)配合物催化CO2和环氧化合物合成环状碳酸酯反应中取得的重大进展,尤其是催化合成手性环状碳酸酯的化学选择性问题.

Salen -Co（Ⅲ ） complexes that catalyze the formation of cyclic carbonates by cycloaddition of CO/and epoxides used the greenhouse gas as theraw material to synthesize useful molecules, meanwhile, the reaction is consistent with atomiceconomy and it is one of the most promising green processes. This paper discusses the significant progress of the formation of cyclic carbonates by cycloaddition of CO2 to epoxides catalyzed by Salen - Co （Ⅲ ） complexes. In particular, the chemical selectivity of catalytic synthesis of chiral cyclic carbonate is also discussed.
