Copper-Catalyzed Allylic Oxidation of Cyclohexene with Molecular Oxygen

Copper-catalyzed aerobic allylic oxidation of cyclohexene under solvent-free conditions leads to 2-cyclohexenol and 2cyclohexenone, the important intermediates in chemurgy. This pathway is suitable for industrial production, owing to the high conversion rate and selectivity, the solvent-free conditions, the cheap catalyst and the environment-friendly oxidant and procedure.
