摘要

In this contribution, we report the successful utilization of several transition metal complexes based on substituted N_4-N,N-bis(2-pyridinecarboxamide)-1,2-benzene chelating ligands as catalysts in the coup- ling of epoxides with carbon dioxide. The complexes were tested towards cyclohexene oxide and pro- pylene oxide. Additionally the recyclability of the catalytic system was evaluated and a broader catalytic screening involving several commercially available epoxides was carried out with selected catalysts.
