Article abstract of DOI:10.1039/DT9930003647

The oxygen affinities and properties of oxygen adducts of complexes has been studied by cyclic voltammetry and IR, electronic and ESR spectroscopy.The complexes exhibited oxygen-binding ability in the presence of an appropriate axial base ligand (B), and the oxygen adducts were of the end-on bonded Co^III(O2(1-)) type (CoL(B)(O2)>.More complete electron transfer from the metal centre to the oxygen was indicated compared to that with .Electron-donating substituents gave higher concentrations of the oxygen adducts.The superior catalytic activity of these complexes, especially the Me- and Bu^t-substitued derivatives, in the oxygenation of 2,6-di-tert-butylphenol to the corresponding quinone is interpreted in terms of the reactivity of the co-ordinated oxygen and the oxygen affinity of the complexes.
