PROBLEM TO BE SOLVED: To obtain an oxide corresponding to a substrate at a high conversion ratio and a high selectivity by oxidizing the substrate with molecular oxygen under mild conditions. SOLUTION: Under the existence of an oxidizing catalyst consisting of an imide compound (N-hydroxyphthalimide and the like) represented by a formula (wherein R<1> and R<2> represent substituents such as hydrogen atom, halogen atom and the like, and R<1> and R<2> may be bonded with each other to form a double bond or an aromatic or nonaromatic 5-12 membered ring. X represents O or HO and n=1 to 3) and an auxiliary catalyst (excluding phosphovanado molybdic acid) containing elements selected from the group of 2A group in the periodic table, transition metals (3A group - 7A group, 8 group and 2B group in the periodic table) and 3B group in the periodic table, a substrate (cycloalkanes, polycyclic hydrocarbons and aromatic compounds having methyl group or methylene group adjacent aromatic ring) is oxidized to obtain oxides (ketones, alcohols, carboxylic acid and the like). |
