| titleOfInvention | Nitrogen-oxygen-containing radical-containing oxygen-free radical sym-terphenyl (triazine) tricarboxylic acid copper complex and application thereof in preparation of menadione |
| abstract | The invention belongs to the field of organic synthesis, and particularly relates to a copper tris (hydroxy) arylbenzene (triazine) tricarboxylate complex containing nitroxide free radicals and an application of the copper tris (hydroxy) arylbenzene (triazine) tricarboxylate complex in preparation of menadione. The structural formula of the copper tri-aryl benzene (triazine) tricarboxylate complex containing nitroxide radicals is shown as a formula I, wherein X is C or N; r 1 is-H, -CH 3 、‑C 2 H 5 or-OCH 3 ，R 1 Can be in any position on the aromatic ring; r 2 And R 3 is-H, -CH 3 or-Cl, R 2 And R 3 May be the same or different. The compound has a novel structure, can be used as a stable and high-activity heterogeneous copper catalyst to efficiently catalyze and oxidize methylnaphthalene to synthesize menadione, can avoid using strong oxidants such as chromic acid and hydrogen peroxide, has mild reaction conditions, high yield, can be recycled, is economical and efficient in reaction, and has a wide application prospect. |
