Copper Oxide(CuO) nanoparticles and nanoporous silica such as MCM-41 and SBA-15 were synthesized and characterized by Fourier Transform InfraRed (FT-IR) spectroscopy, X-Ray Diffraction (XRD), and Sscanning Electron Microscopy (SEM). The synthesized copper oxide nanocatalyst was applied in allylic oxidation of cycloolefinsvia C–H bonds activation by tert-butyl-p-nitrobenzoperoxoate as oxidant and in the presence of nanoporous silica as additive. Allylic esters were obtained in good yields (up to 90%) and reasonable reaction times. Also, the recovered catalyst was applicable in the allylic oxidation reaction for four times without loss in catalytic reactivity and yield. The structure of tert-butyl-p-nitrobenzoperoxoate and allylic esters were characterized by 1HNMR, and 13CNMR spectroscopy
