(57) [Summary] [Objective] Under mild conditions, a substrate is efficiently oxidized by molecular oxygen to obtain a target oxidation compound with high reaction conversion and selectivity. [Structure] An oxidation catalyst composed of an imide compound such as N-hydroxyphthalimide represented by the general formula (1), or the above imide compound and a transition metal compound (for example, oxide, halide, complex, heteropolyacid salt, etc.) In the presence of an oxidation catalyst composed of a co-oxidizing agent such as, for example, a substrate such as hydrocarbons, alcohols, aldehydes and ketones is brought into contact with molecular oxygen to oxidize. Oxidation of cyclohexane gives cyclohexanone, cyclohexanol or adipic acid with high conversion and selectivity.

May form a ring, X represents O or OH, and n = 1 to 3) |
