The synthesis method of 4-fluoro-2- (trifluoromethyl) benzene-1-sulfonyl chloride can follow the following path.
First, benzene containing a specific substituent is used as the starting material. The fluorine atom and trifluoromethyl are introduced into the benzene ring first, often by electrophilic substitution reaction. Appropriate fluorine-containing reagents and trifluoromethylation reagents are selected, and under suitable reaction conditions, such as in a specific catalyst and temperature environment, the fluorine atom and trifluoromethyl are precisely connected to a specific position in the benzene ring to form a benzene derivative with a corresponding substituent.
Then, for another position on the benzene ring, a sulfonyl chloride group is intended to be constructed. Sulfonic acid groups are often introduced into the benzene ring by means of a sulfonation reaction, using concentrated sulfuric acid or fuming sulfuric acid as sulfonation reagents. This reaction requires fine regulation of the reaction temperature and time to prevent excessive sulfonation. The resulting sulfonic acid derivatives interact with chlorinated reagents such as phosphorus pentachloride and sulfinyl chloride. Taking phosphorus pentachloride as an example, under heating and other conditions, the sulfonic acid group can be converted into a sulfonyl chloride group, and the target product 4-fluoro-2- (trifluoromethyl) benzene-1-sulfonyl chloride is obtained.
Second, there are also methods for gradually constructing target molecules through multi-step reactions with other compounds as starting materials. The intermediate containing part of the target structure is first synthesized, such as the specific structural fragment containing fluorine and trifluoromethyl, and this fragment has functional groups that can be further derived. Then, through suitable reactions, such as nucleophilic substitution, oxidation, etc., groups related to the structure of sulfonyl chloride are gradually introduced into this intermediate. After multi-step transformation and modification, the synthesis of 4-fluoro-2- (trifluoromethyl) benzene-1-sulfonyl chloride is finally achieved. Although this approach has many steps, the synthesis route can be flexibly optimized according to the combination of different starting materials and reaction conditions to improve the yield and purity of the product.
