| titleOfInvention | A kind of preparation method of polyaryl-substituted m-phenylenediamine derivative |
| abstract | The present invention relates to the invention discloses a preparation method of polyaryl-substituted m-phenylenediamine derivatives. In an organic solvent, m-dihalogenated arene and two substituted aniline monomers are added at a certain temperature, and the copper catalyst And under the action of alkali, the product polyaryl-substituted m-phenylenediamine derivative is finally obtained. The method of the invention adopts a copper catalyzed reaction to prepare polyaryl-substituted m-phenylenediamine derivatives, and the preparation method is safer and more convenient, has low production cost, high total yield and less waste, and is favorable for industrialization. |
