Abstract
A zeolite immobilized hybrid catalyst [Cu(bpy)2]2+NaY [bpy = 2,2′-bipyridine](1) was prepared by immobilizing Cu(II)-bipyridine complex onto NaY zeolite and characterized by spectral methods. X-ray powder diffraction analysis of 1 revealed that the structural integrity of the mother zeolite in the hybrid material remained intact upon immobilization of the complex. Spectroscopic studies showed that the coordination geometry of 1 undergoes a significant distortion when it is entrapped in the zeolite cavity. The catalytic oxidation of a series of alkenes was carried out with the neat and the immobilized complexes in the presence of the ecofriendly oxidant tert-BuOOH (TBHP) at an ambient condition. The catalyst exhibited excellent catalytic potency and product selectivity, with respect to the neat complex in these reactions. The activity of the immobilized catalyst remained nearly the same after several cycles, indicating the true heterogeneous nature of the catalyst.
