Title:
OXIDATION CATALYST AND OXIDATION METHOD USING THE SAME
Document Type and Number:
Japanese Patent JP3854344
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a target oxidized compound with a high rate of reaction conversion and selectivity by oxidizing effectively a substrate with molecular oxygen under mild conditions.
SOLUTION: Under the presence of an oxidation catalyst consisting of an imido compound such as N-(9-fluorenyloxi) phthalimide represented by the formula or an oxidation catalyst consisting of a cooperating oxidizing agent including the imido compound and a transition metal compound, substrate, such as a cyclic compound is oxidized by being brought into contact with molecular oxygen, e.g. fluorenone is obtained from fluorene with a high conversion selectivity in the formula R1 and R2 are identical or different, and each represents a hydrogen atom, a halogen atom, an alkyl group, an aryl group, a cycloalkyl group, a hydroxyl group, an alkoxy group, a carboxyl group, an alkoxycarbonyl group, and an acyl group, R1 and R2 may link with each other to form a double bond, or an aromatic or non-aromatic ring, R3 represents a ring group having tertiary carbon at the bonding site to an adjacent oxygen atom, and n represents an integer of 1-3.
