To prepare 2-fluoro-6- (trifluoromethyl) benzene-1-sulfonyl chloride, various organic synthesis methods are often followed. First, benzene derivatives containing corresponding substituents can be started. First introduce fluorine atoms and trifluoromethyl groups into the benzene ring, and then try to introduce sulfonyl chloride groups.
If benzene containing a suitable substituent is used as a substrate, an electrophilic substitution reaction can be used to guide fluorine atoms into the benzene ring. For example, with a suitable fluorine substitution reagent, with the help of a catalyst, the fluorine atom is substituted for the hydrogen atom at a specific position in the benzene ring.
