Abstract Polarography and electrolysis/EPR were used to study the electrochemical reduction of the complex of Zn(II) with 4-(2′-oxopropylidene)-2,2,5,5-tetramethyl-3-imidazolidine-1-oxyl in acetonitrile. The reaction center in the electron transfer to the protonated ligand LH is the nitroxyl radical. It has been found that E1/2 of the reduction is highly sensitive toward the presence of proton donors. A stepwise reduction of the radical centers of the ligands in stages has been established in the ZnL2 complex. It has been concluded that exchange reactions take place between the products of two- and three-electron reduction and the initial molecule.
