Abstract	The coordination behavior of transitional metals (Co, Cu, Mn, Fe) with Schiff bases has been investigated and a considerable number of complexes obtained have been characterized by the usual spectroscopic methods (UV-VIS, FT IR, NMR, EPR). For some of these complexes studies concerning their dioxygen uptake ability and their catalytic activity regard oxidation processes were carried out. The present work reports the synthesis, spectral characterization and catalytic activity of new copper (II) coordination compounds with tetra-chlorinated Schiff bases derivatives of the salen and salophen [salen = bis(salicyliden)ethyenediamine and salophen = bis(salicyliden)-o-phenylenediamine] type. The electrochemical properties of the complexes were studied by cyclic voltammetry. The catalytic activity of the complexes was studied with regards to the oxidation of 2,6-di-t-butylphenol. It was seen that the aliphatic substituents on the azomethinic groups and the chloro grafted on the ligand molecules modified the redox and catalytic properties of the complexes.
