Abstract: The oxidation of cyclohexene to cyclohexanone catalyzed by Pd(OAc)2/HQ/FePcwas investigated in an acidic aqueous solution of acetonitrile.The role of each component incatalyst system during the oxidation of cyclohexene was examined by UV-Vis,IR,XPSspectroscopy and cyclic voltammetry, respectively.Based on the experimental results,themechanism of oxidation of cyclohexene catalyzed by Pd(OAc)2/HQ/FePc was discussed.

Key words: cyclohexene oxidation, cyclohexanone, Pd(OAc)2, hydroquinone, phthalocyanineiron, reaction mechanism
