The synthesis of 4-fluorobenzene-1,2-dinitrile is a key research in the field of organic synthesis. There are many ways to synthesize it, and each has its own advantages.
First, fluorobenzene derivatives are used as starting materials and can be prepared by cyanylation reaction. Usually 4-fluorobenzoic acid is used as the starting point, and it is first converted into the corresponding acid chloride, and then reacted with cyanide reagents, such as cuprous cyanide. In this process, the nucleophilic substitution of acid chloride and cuprous cyanide occurs, and then the cyanide group is introduced. The reaction conditions are quite critical, and strict temperature control and time control are required, and the pH of the reaction system also has a great influence on the reaction process and yield.
Second, halogenated aromatic hydrocarbons can also be used as raw materials. For example, 4-fluoro-1,2-dihalogenated benzene reacts with cyanide reagents under the action of suitable catalysts. Commonly used catalysts such as palladium catalysts can effectively promote the reaction of cyano-substituted halogen atoms. This method requires fine selection of catalysts and ligands to improve the selectivity and activity of the reaction. And the choice of reaction solvent cannot be ignored. Different solvents have different effects on the reaction rate and product distribution.
Third, from the perspective of benzene ring construction, the benzene ring structure is constructed through multi-step reaction with suitable fluorine-containing and cyanide-containing small molecules. Although this strategy is complicated, it can precisely control the position and type of substituents on the benzene ring. Each step of the reaction needs to be cleverly planned to ensure the yield and selectivity of each step, and the separation and purification of intermediates are also key links.
