A novel heterogeneous catalyst [Star-Cu(OAc)2] was prepared by chemically immobilizing copper (II) acetate onto the surface of organically modified starch and its catalytic activity was evaluated for the oxidative aromatization of 1,3,5-trisubstituted pyrazolines to corresponding pyrazoles using molecular oxygen as oxidant. The catalyst was found to be quite active and selective under the selected reaction conditions and could be easily recovered by simple filteration. Moreover, the catalyst can be reused without significant loss of activity.
