摘要

The following bidentate Schiff base: 2-[(4-Methoxybenzyl)iminomethyl]-phenol (HL), was employedas an asymmetric ligand in the synthesis of two mononuclear nickel(II) and cobalt(III) complexes(Ni(II)-2L and Co(III)-3L). This ligand has been synthesized via condensation of salicylaldehyde and4-methoxybenzylamine in methanolic solution, while the both complexes result from complexation ofmetal(II) chloride hydrate salts with HL. These coordination compounds were structurallycharacterized by elemental analysis, FT-IR, UV-Vis, 1H NMR and 13C NMR spectral studies.Moreover, the electrochemical properties of both complexes were studied by cyclic voltammetry inDMF solution containing 0.1 M tetra-n-butylammonium tetrafluoroborate (Et4NBF4). This studyreveals that each complex showed successively two redox couples: M(III)/M(II) and M(II)/M(I).Finally, the electrocatalytic activity of these complexes has been examined and it has been found thatthe both complexes worked as effective homogeneous electrocatalysts for the electroreduction ofbromocyclopentane and iodobenzene using glassy carbon as working electrode.
