Abstract

Two novel copper (II) complexes containing thiosemicarbazones supported on nanoporous silica gel, [CuL2-SiO2] and [CuL’2-SiO2] were prepared by direct sol–gel method. The material was characterized by physico-chemical characterization, SEM and TEM methods. These complexes were found to be competent catalysts for selective oxidation of primary and secondary alcohols using hydrogen peroxide as an environmentally friendly oxidant. The catalysts could easily be recycled and reused without noticeable loss of activity.
