Full Papers


Cyclic voltammetric studies on the reduction of the title complexes were carried out in aqueous media at HMDE. The histidine-containing mixed amino acid copper(II) complexes exhibit a relatively sharp reduction peak which is identified with an adsorption-controlled reduction process. The histidine-containing copper(II) dipeptide complexes undergo a one-electron reduction generating an intermediate copper(I) species which subsequently decomposes to Cu0. The mechanism of these processes is discussed. The cyclic voltammograms of these complexes are not complicated by adsorption processes.
