Cyanuric fluoride is a chemical compound selected from the group of triazines.

Production and representation

Cyanuric fluoride can be obtained at 134 ° C by the reaction of cyanuric chloride with hydrogen fluoride at 40 ° C, or with sodium fluoride in acetonitrile.

Properties

Cyanuric fluoride is a flammable, colorless to yellowish liquid with a pungent odor, which decomposes in water. It is hydrolyzed by dilute hydrofluoric acid to cyanuric acid. Cyanuric fluoride is more reactive than cyanuric chloride.

Use

Cyanuric fluoride is used for mild and direct conversion of carboxylic acids to carboxylic acid fluorides:
