Allylic oxidation of cyclohexene catalyzed by chitosan Schiff base cobalt catalyst

A chitosan-schiff base cobalt comples( CS-Schiff base-Co) was prepared and characterized by X-ray diffraction,infrared spectroscopy and TG method,as well as the catalytic properties of this complex in oxidation of cyclohexene were studied in the presence of oxygen. And the influences of the amount of catalyst,reaction temperature and reaction time on oxidation were also investigated. These results indicated that CS-Schiff base-Co catalyst had excellent catalytic activity and selectivity for the allylic oxidation in cyclohexene. The conversion and selectivity were 85. 3% and 81. 3% under suitable conditons,respectively. The catalyst was perfectly leach-proof and could be resued at least four times.
