Chitosan, a natural polymer, bound Schiff base copper complexes CT-She-Cu, CT-o-Bel-Cu, CT-m-Bel-Cu were prepared and characterize by inductively coupled plasma (ICP), FT-IR and X-ray photoelectron spectroscopy (XPS). Their catalytic activity in the oxidation of cyclohexene with molecular oxygen was studied. All the complexes have catalytic activity and the main oxidation products are 2-cyclohexene-ol, 2-cyclohexene-one and cyclohexene hydroperoxide, which were measured by gas chromatography/mass spectroscopy (GC/MS) and GC/IR. CT-m-Bel-Cu was selected to study the influence of reaction temperature, amount of catalyst and additives such as acid and base on the oxidation of cyclohexene systematically.
