- Preparation method of trifluoroacetophenone derivative
-
The invention relates to the field of organic synthesis, in particular to a preparation method of a trifluoroacetophenone derivative. Substituted aniline is used as a raw material, and preparation of the trifluoroacetophenone derivative is completed through three steps including diazotization reaction, coupling reaction and hydrolysis reaction. The preparation method has the advantages of simple process, high yield and less three wastes generated by the whole reaction, and is suitable for large-scale industrial production.
