摘要
In order to reduce mankind's carbon footprint and thus reducing the environmental toll of human activities, it is necessary to implement industrial technologies to convert carbon dioxide in added-value products, from which polycarbonates represent an important category. This review discusses the development of catalytic systems for the ring-opening copolymerization (ROCOP) of epoxides and CO2 to produce polycarbonates, focusing on those systems made from earth-abundant metals. Since the ROCOP of epoxides and CO2 commonly proceed through a multinuclear mechanism, this account focuses only on bi-and multimetallic heterogeneous catalytic systems developed from 1985 onwards and homogeneous catalysts reported after 2015, giving emphasis on the structural features of these complexes and their corresponding reactivities.
