A substrate is contacted with oxygen in the presence of the imide compound shown by the following formula (1) (N-hydroxyphthalimide) and a strong acid, or the imide compound, the strong acid and a co-catalyst (e.g., a transition metal compound) to oxygenate the substrate with high conversion and selectivity: <CHEM> wherein R<1> and R<2> represent a substituent such as a hydrogen atom or a halogen atom, an alkyl group, an aryl group or a cycloalkyl group, or R<1> and R<2> may bond together to form a double bond or an aromatic or nonaromatic ring, X is O or OH, and n is 1 to 3. The substrate comprises, for example, at least one compound selected from (a) a compound having a methyl group or a methylene group at an adjacent site of an unsaturated bond, (b) a homo- or hetero cyclic compound having a methylene group, (c) a compound having a methine carbon atom, (d) a compound having a methyl group or a methylene group at an adjacent site of an aromatic ring and (e) a compound having a methyl group or a methylene group at an adjacent site of a carbonyl group. |
