| titleOfInvention | A kind of preparation method of 3,5-dihalotrifluoroacetophenone and its derivatives |
| abstract | This application relates to the technical field of chemical and pharmaceutical industry, especially to a preparation method of 3,5-dihalotrifluoroacetophenone and its derivatives, using 3-halogen-4-nitrotrifluoroacetophenone as raw material, After reduction reaction, halogenation reaction and amino substitution reaction, the derivatives of 3,5-dihalotrifluoroacetophenone are finally obtained. The raw materials are cheap and easy to obtain, the process is simple, the conditions are mild, and it has the prospect of large-scale production. Good economic effect. |
