| titleOfInvention | A kind of β-trifluoromethylaniline compound and preparation method thereof |
| abstract | The invention provides a preparation method of β-trifluoromethylaniline compounds, belonging to the technical field of organic synthesis. The invention uses the organic dye Rose Bengal as a catalyst, has low cost, and has good catalytic effect; the invention is a one-step reaction, and the β-trifluoromethylaniline compound can be obtained from the alkaline raw material mixed solution under illumination conditions. In the present invention, the Togni reagent generates a trifluoromethyl radical under the irradiation of light, which is then added to an alkene to form a β-trifluoromethyl radical intermediate, which is further oxidized to a radical cation, and then captured by a pro- The target product is obtained by the aniline radical generated by the nuclear reagent phenylhydrazine. The invention utilizes the irradiation of light to provide energy, the reaction process is stable, the conditions are mild, the control is easy, and the obtained product has high purity. The results of the examples show that the purity of the β-trifluoromethylaniline compounds obtained by the method of the present invention can reach 99.9%. |
