Abstract: Copper(II) paratolylsulfonate [Cu(p-OTs)]2 has been synthesized and characterized by X-ray crystal structure analysis. The electrochemical parameters of Cu(p-OTs)2 in H2O, CH3OH and DMF have been studied on platinum electrode, respectively. Different reaction mechanisms in different solvents are found. The electrochemical reduction of Cu(II) to Cu proceeds by two one-electron steps in H2O. However, it is a one two-electron process in CH3OH and DMF.
