Application

 

The primary commercial use of iron(III) fluoride in the production of ceramics. Some cross coupling reaction are catalyzed by ferric fluoride-based compounds. Iron(III) fluoride has also been shown to catalyze chemoselective addition of cyanide to aldehydes to give the cyanohydrins.
