2,6-Difluorobenzonitrile Usage And Synthesis

Chemical Properties

white to light yellow crystal powder

Uses

2,6-Difluorobenzonitrile was used in the synthesis of:

• poly(cyanoaryl ethers) via silyl-method
• 2-dimethylamino-6-fluorobenzamide
• phenolphthalein-modified polyarylene ether nitrile copolymers

Uses

2,6-Difluorobenzonitrile is a halogenated benzonitrile with fungacidal activity. 2,6-Difluorobenzonitrile is the difluoro analogue of the herbicide Dichlobenil.

Flammability and Explosibility

Non flammable

Synthesis

2,6-Difluorobenzonitrile [1897-52-5], 1- cyano-2,6-difluorobenzene, Mr 172.02, mp 29 – 30℃, forms colorless crystals. The nitrile can be produced by treatment of 2,6-dichlorobenzonitrile with potassium fluoride in sulfolane and is used as an intermediate in the synthesis of insecticides (e.g., Dimilin, Shell).
