Abstract:

 The redox reaction of the aliphatic complexes [M(Ⅱ)(PnAO) H]+(M=Ni, Co, Cu, Pd) were studied by cyclic voltammetry. The CV data of these reactions were determined. A reasonable mechanism was proposed, which is a coupled mechanism of electrochemical and chemical reactions. The influence of metal ions and pH upon the formation of the quasiaromatic metal complexes was discussed. Furhtermore, it indicates that the absence of quasi-aromatic ring formed in some cases is due to kinetic properties, not thermodynamic reasons.
