To prepare 2,6-difluoro-4- (trifluoromethyl) benzene-1-sulfonyl fluoride, there are many methods, which are described in detail below.
First, fluoroaromatic hydrocarbons are used as starting materials. Schilling fluoroaromatic hydrocarbons are introduced into sulfonyl groups through specific substitution reactions. In this step, suitable sulfonating reagents, such as fuming sulfuric acid, etc., and the reaction conditions, such as temperature, time and reactant ratio, need to be precisely regulated to ensure that the sulfonation reaction occurs efficiently and accurately at a specific position in the benzene ring. Then, for the obtained sulfonyl-containing intermediate, the sulfonyl group is converted into sulfonyl fluoro group through halogenation reaction with a suitable halogenating agent, such as halogenated sulfoxide. At the same time, during the reaction process, close attention should be paid to the selectivity and conversion rate of the reaction, and the reaction conditions should be optimized in a timely manner.
Second, benzene derivatives can be used. First, a series of substitution modifications are carried out on the benzene ring, and fluorine atoms and trifluoromethyl atoms are introduced in sequence. When introducing fluorine atoms, nucleophilic substitution or electrophilic substitution can be used, depending on the specific reactants and reaction conditions. There are also various methods for introducing trifluoromethyl, such as using trifluoromethylation reagents under the action of appropriate catalysts. After the specific substituted benzene ring structure is successfully constructed, the introduction of sulfonyl fluoro groups is carried out. This step also requires fine control of the reaction conditions to ensure the purity and yield of the product.
Third, with the help of transition metal catalysis reaction strategy. Use suitable transition metal catalysts, such as palladium, nickel and other complexes, to catalyze the coupling reaction between fluorine-containing substrates and sulfonyl fluoride-based reagents. This approach requires careful selection of catalysts and ligands, optimization of the type and amount of reaction solvent and base, so as to improve the activity and selectivity of the reaction, and promote the efficient progress of the reaction in the direction of generating the target product.
All these methods have advantages and disadvantages. In the actual synthesis, it is necessary to consider many factors such as the availability of raw materials, cost, difficulty in controlling reaction conditions, and the purity and yield of the product, and carefully choose the optimal synthesis path to achieve the purpose of efficient preparation of 2,6-difluoro-4- (trifluoromethyl) benzene-1-sulfonyl fluoride.

2% 2C6-difluoro-4- (triethoxymethyl) benzene-1-sulfonyl fluoride is a fine chemical. During storage and transportation, many matters need to be paid special attention.
When storing, the first environment. Be sure to store in a cool, dry and well-ventilated place. This substance is afraid of heat and moisture. If the ambient temperature is too high or the humidity is too high, it is easy to change its properties and even cause danger. Therefore, the warehouse temperature should be controlled within a certain range, and the humidity should also be strictly standardized.
Furthermore, it should be properly isolated from other substances.
