Generally speaking, the temperature needs to be precisely controlled within a certain range according to the specific reaction mechanism and the characteristics of the reagents used.
Second, or it can be obtained by gradual conversion of other functional groups. If nitro is introduced first, then trifluoromethyl and chlorine atoms, or vice versa. In this process, the order and conditions of each step of the reaction also need to be carefully considered. When introducing nitro, a mixed acid system of nitric acid and sulfuric acid is commonly used, but its concentration, reaction time and other factors will affect the location and yield of nitro introduction.
Introducing trifluoromethyl often requires special reagents and reaction paths. Or use a reagent containing trifluoromethyl, in the presence of an appropriate catalyst, to substitution with the substrate. For the introduction of chlorine atoms, chlorinated reagents, such as thionyl chloride, can be selected. According to the structure of the substrate and the reaction environment, the reaction parameters can be adjusted to achieve the best reaction effect.
