Abstract

Mixed valence cobalt (II, III) systems, one binuclear Co ^IIICo^II (1) and another novel cyclic trinuclear Co ^IIICo^II₂ (2) complexes based on hydroxyl rich Schiff base ligands are synthesized and structurally characterized by X-ray crystallography. Catalytic activity of 1 and 2 towards oxidation of 3, 5-di-tert-butylcatechol (3,5-DTBC) to its corresponding quinone (3,5-DTBQ) are investigated in MeOH and DMF. ESI-MS technique is employed to characterize the intermediates.
