Synthesis, characterization, electrochemical studies and catecholase-like activity of a series of mononuclear Cu(II), homodinuclear Cu(II)Cu(II) and heterodinuclear Cu(II)Ni(II) complexes of a phenol-based compartmental ligand

The initial rate of the oxidation of catechol to corresponding quinone was examined in the presence of a series of novel or previously reported mononuclear Cu(II), homodinuclear Cu(II)Cu(II) and heterodinuclear Cu(II)Ni(II) complexes. It is found that the homodinuclear complexes are more effective catalyst compared to the other complexes.
