Easy-to-handle ionic transition metal complexes in the formation of carbonates from epoxides and CO2: A N4-ligand system based on N,N-bis(2-pyridinecarboxamide)-1,2-benzene

In this contribution, we report the successful utilization of transition metal complexes based on an inexpensive and easy-to-handle N4-chelating ligand as catalysts of the coupling of epoxides with carbon dioxide. The complexes were tested towards a range of epoxides within a catalytic screening, varying various experimental parameters like e.g. concentration of catalyst, temperature and pressure.

Graphical abstractWe report the successful utilization of transition metal complexes based on an inexpensive and easy-to-handle N4-chelating ligand as catalysts of the coupling of epoxides with carbon dioxide. The complexes were tested towards standard epoxides within a catalytic screening, varying various experimental parameters like e.g. concentration of catalyst, temperature and pressure.Figure optionsDownload full-size imageDownload as PowerPoint slide
