≥99% 3,4-Difluorobenzonitrile

C₇H₃F₂N

CAS No.: 64248-62-0

34-Difluorobenzonitrile CAS No 64248-62-0

Application

The capacity of 2,4-difluorobenzonitrile to function as a building block in the synthesis of materials, agrochemicals, and pharmaceuticals makes it a significant and adaptable organic compound used in many different industries. Despite its benefits, handling this chemical requires appropriate safety measures because of its flammability and toxicity.

Carbon dioxide and ammonia reduction method: This process creates 3,4-difluorobenzonitrile by reacting carbon dioxide and ammonia with 3,4-difluorochlorobenzene, reducing agent, organic solvent, nickel catalyst, and ligand. The following are the precise steps: Add ammonia and carbon dioxide to a gas that contains ligands, nickel catalysts (like NiI2, NiCl2·DME, etc.), organic solvents, reducing agents (like Cl3SiH, PhSiH3, Et3SiH), and 3,4-difluorochlorobenzene. The reaction temperature in the reaction chamber is between 80°C and 200°C, and it takes 6 to 12 hours. When the reaction is finished, the target product is produced.‌
