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.
根据本发明的有机化合物共氧化工艺,(A)选自(A1)具有非芳香族乙烯键的化合物和(A2)酮或与酮相应的醇的化合物,在 N-羟基邻苯二甲酰亚胺或另一种酰亚胺化合物存在下,在(B)可被酰亚胺化合物和氧氧化且不同于化合物(A)的化合物共存的情况下,被分子氧氧化。作为化合物(B),可以使用(a)伯醇或仲醇(如二苯甲醇、环己醇),(b)在与不饱和键相邻位置各具有一个碳-氢键的化合物(如四萘、乙苯)等。根据该工艺,可以从具有非芳香族乙烯键的化合物(A1)中得到相应的环氧化合物,并从酮或其相应的醇(A2)中得到相应的酯或内酯,产率令人满意。
