Phthalocyanine Complex Supported on Polysilsesquioxane: A New and Efficient Catalyst for Oxidation of Benzyl Alcohol

Abstract

In this research, poly organo silsesquioxane with a functional group which contains the chlorine atom has been prepared to support a functionalized phthalocyanine complex. The prepared catalyst has been characterized with powder X-ray diffraction pattern, field emission scanning electron microscopy and infrared spectroscopy. This catalyst was then used for catalytic oxidation of benzyl alcohol and some parameters in this model reaction have been optimized such as the type of oxidant and solvent, amount of catalyst, reaction temperature and time. It was found that the optimum conditions are 40 mg catalyst in acetonitrile as solvent with tert-butylhydroperoxide as oxidant at 82 C which gives 70% yield.
