transform infrared (FT-IR) spectroscopy. The result of the heterogeneous catalysts being applied in the monometallic direct catalytic esterification of sp3 C–H bonds in cyclic olefins for the first time is reported, using tert-butyl 4-nitrobenzoperoxoate at room temperature. Allylic esters were obtained as the product of the C–H bond oxidation reaction in moderate to good yields (up to 99%) within reasonable
