Molecular oxygen catalyzed by amino acid Schiff base Mn complex (Sal-Phe-Mn) effectively oxidized cyclohexene. 2-Cyclohexen-1-ol (-OH), 2-cyclohexen-1-one (C = O) and 2-cyclohexen-1-hydroperoxide (-OOH) were the major products of the reaction, which were different with typical oxidation of cyclohexene. The selectivity of 2-cyclohexen-1-hydroperoxide varied with reaction time and different additives. Rapid oxygen consumption was observed in the presence of acetate acid at 343 K. The cyclohexene oxidation rate was 1.1 times with that of no additive. The addition of pyridine into the oxidation system reduced the rate of O2 consumption quickly, which was 24% with that of no additive. The allylic hydroperoxide was obtained as an essential product, suggesting a clear allylic pathway of oxidation of cyclohexene.
