Oxidative dehydrogenation of 5-(pyridine-2-yl-methyl)-2-thioxo-4-imidazolidinones in complexation reaction with copper(II) chloride

• 3,5-Dihydro-4H-imidazole-4-ones undergo oxidation in complexation reactions with CuCl2·2H2O.
• Delocalized mixed-valence complexes with a [Cu+ 1.5Cu+ 1.5] redox state are obtained.
• Crystal structures of obtained complexes are confirmed by X-ray data.

The treatment of 5-(pyridine-2-yl-methyl)-2-thioxo-4-imidazolidinones with copper(II) chloride dihydrate led to the formation of a dinuclear copper complex L2Cu2Cl where L is a dehydrogenated initial organic ligand. X-ray diffraction analysis indicated that the starting 3,5-dihydro-4H-imidazole-4-ones undergo oxidation in the course of the reaction with the formation of an exocyclic double bond at C5 position.
