What is 3-AMINO-4-FLUOROBENZOTRIFLUORIDE chemical synthesis method?

The chemical synthesis of 3-amino-4-fluorotrifluorotoluene can be achieved by the following steps.

First, a suitable starting material is obtained, and fluorobenzene-containing compounds are often used as the base. Taking a fluorobenzene derivative as an example, under specific reaction conditions, the nitrogenation reaction is first carried out. This reaction requires careful temperature control and the selection of suitable nitrifying reagents, such as a mixed acid of concentrated nitric acid and concentrated sulfuric acid. Under the action of this mixed acid, nitro groups are introduced into a specific position of the benzene ring to obtain fluorobenzene derivatives containing nitro groups. The reaction mechanism of this step is that the nitrate ion is acted by sulfuric acid to generate nitroyl positive ions, which act as an electrophilic agent to attack the benzene ring and realize the substitution of nitro groups. < Br >
Then, the resulting nitro-containing product is subjected to a reduction reaction. It is often done by catalytic hydrogenation or chemical reduction. If catalytic hydrogenation is used, a suitable catalyst, such as palladium carbon (Pd/C), can be selected to react in a hydrogen atmosphere. This reaction is carried out at a suitable temperature and pressure, and the nitro group is gradually reduced to an amino group, and the target product is 3-amino-4-fluorotrifluorotoluene. The principle is that hydrogen is adsorbed and dissociated on the surface of the catalyst, and the hydrogen atom is reacted with the nitro group, and finally converted into an amino group through a series of intermediate steps.

Or chemical reduction is used, such as a system composed of metal and acid, such as iron and hydrochloric acid, which can also achieve the reduction of nitro groups. Ferrous ions are formed by iron under the action of hydrochloric acid, which acts as a reducing agent to reduce nitro groups. In this process, the metal provides electrons to gradually convert nitro groups into amino groups, and 3-amino-4-fluorotrifluorotoluene can also be obtained. However, the chemical reduction method may produce more by-products and the post-treatment is relatively complicated. In comparison, the catalytic hydrogenation method is cleaner and more efficient.
