Abstract: Three new copper(ii) complexes with different Schiff-base ligands, namely, [Cu(L 1 )Cl 2 ] (1), [Cu 3 (L 2 ) 2 Cl 4 ] (2) and [Cu(L 3 )N 3 ] n (3) where L 1 = 2-morpholino-N-(pyridin-2-ylmethylene)ethanamine, HL 2 = 4-bromo-2-((2-morpholinoethylimino)methyl)phenol and HL 3 = 4-chloro-2-((2-(dimethylamino)ethylimino)methyl)phenol, have been synthesized and characterized by elemental analysis, standard spectroscopic methods, cyclic voltammometry and single crystal X-ray diffraction analysis. The X-ray diffraction analysis confirms the formation of mononuclear (1), trinuclear (2) and polynuclear (3) complexes. These complexes have been applied as catalysts for alcohol oxidation reactions using tert-butyl hydroperoxide (TBHP) as the terminal oxidant under mild conditions. The catalytic reaction mixture has been analyzed by gas chromatography and it shows that the mononuclear complex has the highest conversion while the other two complexes exhibit moderate catalytic activities. The corresponding aldehyde has been obtained as the sole product. The obtained catalysis results have been corroborated with electrochemical studies. © The Royal Society of Chemistry and the Centre National de la Recherche Scientifique.
