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.
根据有机化合物的创新共氧化过程,(A)一种从(A1)具有非芳香族乙烯键的化合物和(A2)与酮相对应的酮或醇中选择的化合物,在N-羟基酞酰亚胺或其他亚胺化合物存在下,与(B)一种可被亚胺化合物和氧气氧化的化合物共同存在,并与(A)化合物不同。作为化合物(B),可以使用(a)伯醇或仲醇(例如,二苯甲醇,环己醇),(b)在非饱和键相邻位置具有碳-氢键的化合物(例如,四氢萘,乙基苯)等。根据这个过程,可以从具有非芳香族乙烯键的化合物(A1)获得相应的环氧化合物,从酮或其相应的醇(A2)获得相应的酯或内酯,并且可以获得满意的产率。
