CO 2 Fixation and PCHC Depolymerization by a Dinuclear β-Diketiminato Zinc Complex

The production of cyclic carbonates and (or) polycarbonates from the coupling of carbon dioxide (CO ) with epoxides is a practical strategy for CO fixation. Chemically recycling of the polycarbonates is also urgently needed for sustainable development of plastics. Here a dinuclear β-diketiminato (BD...

Description
Summary:The production of cyclic carbonates and (or) polycarbonates from the coupling of carbon dioxide (CO ) with epoxides is a practical strategy for CO fixation. Chemically recycling of the polycarbonates is also urgently needed for sustainable development of plastics. Here a dinuclear β-diketiminato (BDI) methyl zinc complex((BDI-ZnMe) , 1) is reported to achieve not only selective cyclic carbonates from cycloaddition of CO to meso-CHO in the presence of cocatalyst, but also effective depolymerization of PCHC into trans-CHC. The trans-CHC can be further transformed into cis-CHC, thus demonstrating great application potentials of this strategy in CO fixation and chemical recycling of plastics.
