Synthesis, characterisation and catalytic activity of Schiff base Cu(II) metal complex

This study reports the synthesis of chitosan anchored Schiff base, ([2-oxo-1H-indol-3-ylidene] amino) chitosan and its Cu (II) metal complex. The complex was characterized by elemental analysis, FT-IR Spectrum, thermogravimetry analysis. The crystallinity of the compound was analyzed by powder X-ray diffraction technique. The catalytic efficiency of complex was studied in the oxidation of alcohols namely propanol, n-butanol, n-hexanol and benzyl alcohol using non toxic ecofriendly and easily available molecular oxygen as an oxidant. Furthermore the effects of various parameters including temperature, catalyst amount and effect of solvent have also been studied. The complex was found a suitable candidate in bringing out the oxidation reactions.
