Cleavage of the C–S bond with the formation of a binuclear copper complex with 2-thiolato-3-phenyl-5-(pyridine-2-ylmethylene)-3,5-dihydro-4H-imidazole-4-one. A new mimic of the active site of N2O reductase

The treatment of the ligands with copper(II) chloride dihydrate led to the formation of a binuclear copper complex with a [Cu+1.5Cu+1.5] redox state as a result of C–S bond cleavage in the course of the reaction. This complex catalyses the electrochemical reduction of nitrous oxide and triphenyl phosphine oxidation under N2O action.
