Abstract: The electrochemical oxidation of Cu(II), Co(II), and Ni(II) complexes and reduction of Fe(III) complexes with a series of substituted N,N'-ethylenebis(monooxo-R-acetoimines) H2N2O2R2, where R = 4-OCH3C6H4, 4-CH3C6H4, C6H5, CH3, 4-FC6H4, 4-ClC6H4, 4-BrC6H4, and 4-NO2C6H4, were investigated by cyclic voltammetry in acetonitrile and methanol solutions at a platinum electrode. The anodic peak potentials for the copper and nickel complexes varied linearly with the Taft resonance substituent constant, whereas for the cobalt and iron complexes such a relationship between the formal potentials and the Taft resonance substituent constant was not observed. The symmetry of redox orbitals is considered.
