Model Complexes for the Active Form of Galactose Oxidase. Physicochemical Properties of Cu(II)− and Zn(II)−Phenoxyl Radical Complexes

Physicochemical properties of the Cu(II)− and Zn(II)−phenoxyl radical complexes of ligand 1H and its 2,4-di-tert-butyl derivative 2H have been examined as models for the active form of galactose oxidase to shed light on the role of the thioether group in the novel organic cofactor.
