Abstract

K. Rajesh¹ and G. Rathika Nath²

Transition metal complexes on polymers were found to be highly efficient in many catalysis reactions. The activity of Fe(III), Co(II), Ni(II) and Cu(II) complexes of polystyrene bound Isoxazole resin have been tested towards the epoxidation of alkenes by the decomposition of hydrogen peroxide. The reactions show a first order dependence on the concentration of both the substrates and the catalyst. The metal complexes having less cross linking at the backbone and ring-activating group near the active site showed high catalytic efficiency.
