Oxidation of cycloolefins was effectively performed under aerobic (1 atm dioxygen) and mild solvent-free conditions using mesoporous CrMCM-41 molecular sieve catalyst. For instance, Cycloolefins (C5–C7) were selectively oxidized to the corresponding α,β-unsaturated ketones (for example, cyclohexene – 52.2% conversion and 71.2% selectivity) and cycloolefins (C8–C12) were oxidized to epoxides (for example, cis-cyclooctene – 50% conversion and >99% selectivity) at 323–353 K for 24 h. The catalytic activity over recycled catalyst remains nearly same.
