Dinuclear Co-based catalysts are used for the coupling reaction of epoxides and CO2 in the presence of a cocatalyst. The easily recyclable catalysts efficiently complete the coupling of CO2 with various epoxides into industrially important cyclic carbonates at low catalyst loading and displayed high catalytic activity under relatively low CO2 pressure and solvent-free conditions. The maximum TON (168 600) and TOF (3333 h-1) obtained in this work are the highest among the reported Co-complexes.
双核钴基催化剂在助催化剂存在下用于环氧化物与二氧化碳的偶联反应。这些易于回收的催化剂在低催化剂负载量下能有效地将二氧化碳与各种环氧化物偶联生成具有工业重要性的环状碳酸酯，并且在相对较低的二氧化碳压力和无溶剂条件下表现出高催化活性。本工作中获得的最大TON（168600）和TOF（3333 h⁻¹）是已报道的钴配合物中最高的。
