The electrochemical oxidation of the Cu(II) and Co(II) complexes with a series of substituted N,N′- ethylenebis(p-R-benzoylacetoneimines) [H2N2O2- (øR)2], where R = OCH3, CH3, H, F, Cl, Br and NO2, was investigated by cyclic voltammetry in acetonitrile at a platinum electrode. The anodic peak potentials for the copper complexes varied linearly with the Hammett substituent constants, whereas for the cobalt complexes no relationship between the mentioned data was observed. The one-electron oxidation process is in both complex types coupled with a following chemical reaction. In the presence of triphenylphosphine the oxidation process of cobalt complexes is preceded by its coordination. Triphenylphosphine has a catalytic effect during copper complex oxidation.
