What is the synthesis method of 2,4,5,6 - tetrafluorobenzene - 1,3 - dicarbonitrile

2% 2C4% 2C5% 2C6 - tetrafluorobenzene - 1% 2C3 - dicarbonitrile, that is, 2,4,5,6 - tetrafluoro-isophthalonitrile, is synthesized as follows:

To prepare 2,4,5,6 - tetrafluoro-isophthalonitrile, it can be achieved by a suitable starting material through several steps of reaction. Usually starting with a compound containing a benzene ring and a suitable substituent.

One method can first take a benzene derivative containing a specific substituent and react with a reagent capable of introducing a cyanyl group to obtain a benzene compound containing a cyanide group. In this process, suitable reaction conditions, such as specific temperature, pressure and catalyst, need to be selected to promote the effective introduction of cyanide groups. For example, with a halogenated benzene derivative and a cyanide reagent, under the action of an appropriate organic solvent and catalyst, the reaction is heated, and the halogen atom is replaced by a cyanide group through nucleophilic substitution.

Then, the obtained cyanide-containing benzene compound is introduced into the fluorine atom. In this step, fluorination reagents are commonly used, and under specific reaction conditions, fluorine atoms are substituted for hydrogen atoms at specific positions on the benzene ring. The fluorination reaction needs to be finely regulated. Due to the special reactivity of fluorine atoms, improper reaction conditions can easily lead to side reactions. For example, a suitable fluorinating agent is selected, and under low temperature or mild heating conditions, the reaction process is controlled, and gradually the four hydrogen atoms on the benzene ring are replaced by fluorine atoms, and finally 2,4,5,6-tetrafluoro-isophthalonitrile is obtained. < Br >
Or first fluorinate the benzene ring to obtain fluorobenzene derivatives, and then introduce cyanide groups through cyanidation. This path also requires careful selection of reaction conditions at each step to ensure that the reaction proceeds in the predetermined direction and improves the yield and purity of the product. In short, the key to synthesizing this compound lies in the precise control of the reaction conditions at each step and the rational design of the reaction path.
