The relative fluoride donor ability: C6F5BrF2 > C6F5IF2 > C6F5IF4 was outlined from reactions with Lewis acids of graduated strength in different solvents.

The reaction of polyfluorinated aromatic compounds with difluorobromium tetrafluoroborate BrF2+*BF4- leads to the products from regiospecific fluorination.Polyfluorinated derivatives of benzene, toluene, and naphthalene are fluorinated to form 1,4-cyclohexadienes, whereas pentafluoropyridine and 3-chlorotetrafluoropyridine are converted into the corresponding 1-aza-1,3-cyclohexadienes.
