    摘要： According to the inventive co-oxidation process of organic compounds, (A) a compound selected from (A1) a compound having a non-aromatic ethylenic bond and (A2) a ketone or an alcohol corresponding to the ketone is oxidized by molecular oxygen in the presence of N-hydroxyphthalimide or another imide compound and in the coexistence of (B) a compound oxidizable by the imide compound and oxygen and different from the compound (A). As the compound (B), (a) primary or secondary alcohols (e.g., benzhydrol, cyclohexanol), (b) compounds each having a carbon-hydrogen bond at the adjacent position to an unsaturated bond (e.g., tetralin, ethylbenzene) and the like can be used. According to this process, a corresponding epoxy compound from the compound (A1) having a non-aromatic ethylenic bond, and a corresponding ester or lactone from the ketone or its corresponding alcohol (A2) can be obtained in satisfactory yields.
