Synthesis method
1. Ethyl o-carboxybenzoate method: Ethyl o-carboxybenzoate is used as raw material and reacts with sulfur tetrafluoride to obtain o-trifluoromethylbenzoyl chloride. The yield is 80%~83%; o-trifluoromethylbenzoic acid is obtained through hydrolysis.
2. O-Trifluoromethylfluorobenzene method: Using o-trifluoromethylchlorobenzene as raw material, it is obtained by Grignard reaction, with a yield of 90%.
Purpose
Used in the synthesis of fluorine-containing fine chemicals such as medicines and pesticides.
