Ni (II) and Mn (II) metal complexes of Schiff base derived from ethylenediamine, succinic acid and formaldehyde. The newly synthesized Schiff base complexes were characterized by elemental analysis, Melting point, conductivity, IR and UV-VIS spectral methods. The complexes have been tested using for the catalytic oxidation of benzylacohol using ecofriendly molecular oxygen as catalyst. The results show that Nickel complex shows highest yield oxidation product as compared to Manganese at 35°C temperature, 90mg catalyst amount and 25 min. time.
