摘要

二氧化碳(CO2)与环氧化物的偶联生产环状碳酸盐和(或)聚碳酸酯是二氧化碳固定的一种实用策略。塑料的可持续发展也迫切需要对聚碳酸酯进行化学回收。本文报道了一种双核β-二酮酸(BDI)甲基锌配合物((BDI- znme) 2,1)，该配合物不仅在助催化剂的存在下，通过CO2环加成生成选择性的环碳酸酯，而且还能有效地将PCHC解聚成反式chc。反式chc可以进一步转化为顺式chc，因此该策略在CO2固定和塑料化学回收方面具有很大的应用潜力。

CO2 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 (CO₂) with epoxides is a practical strategy for CO₂ 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)₂, 1) is reported to achieve not only selective cyclic carbonates from cycloaddition of CO₂ 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 CO₂ fixation and chemical recycling of plastics.

期刊介绍： Chemistry—An Asian Journal is an international high-impact journal for chemistry in its broadest sense. The journal covers all aspects of chemistry from biochemistry through organic and inorganic chemistry to physical chemistry, including interdisciplinary topics. Chemistry—An Asian Journal publishes Full Papers, Communications, and Focus Reviews. A professional editorial team headed by Dr. Theresa Kueckmann and an Editorial Board (headed by Professor Susumu Kitagawa) ensure the highest quality of the peer-review process, the contents and the production of the journal. Chemistry—An Asian Journal is published on behalf of the Asian Chemical Editorial Society (ACES), an association of numerous Asian chemical societies, and supported by the Gesellschaft Deutscher Chemiker (GDCh, German Chemical Society), ChemPubSoc Europe, and the Federation of Asian Chemical Societies (FACS).
