[PROBLEMS] To efficiently nitrate or carboxylate a substrate even under relatively mild conditions. SOLUTION: In the presence of an imide compound represented by the following formula (1) (such as N-hydroxyphthalimide), a substrate is selected from (i) a nitrogen oxide and (ii) a mixture of carbon monoxide and oxygen. Then, the substrate is brought into contact with at least one type of reactant to introduce at least one type of functional group selected from a nitro group and a carboxyl group into the substrate. Embedded image (In the formula, R 1 and R 2 are a hydrogen atom, a halogen atom, an alkyl group, an aryl group, a cycloalkyl group, R 1 And R 2 may combine with each other to form a double bond or an aromatic or non-aromatic ring. Y is O or OH, n = 1 to 3) Compounds represented by the formula N x O y (N 2 O 3, etc. NO 2) contains, in the substrate, a compound having a methine carbon atom, such as adamantane, and the like compounds having a methyl group or methylene group at the adjacent site of an aromatic ring. |
