Three water-soluble copper(ii) N-heterocyclic carbene complexes: toward copper-catalyzed ketone reduction under sustainable conditions

Abstract

A series of tridentate copper(ii) N-heterocyclic carbene (NHC) complexes with imidazole, benzimidazole, and 5,6-dimethylbenzimidazole azole rings were synthesized and comprehensively characterized via X-ray crystallography, ESI-MS, CV, and UV-Vis and EPR spectroscopic studies.
