process for preparing hypofluorites and bis-hypofluorites, respectively of formula: (i) fso₂-r f -cf₂of and (ii) focf 2 -r' f -cf₂of wherein r f is perfluoroalkylene or perfluorochloroalkylene having from 1 to 4 carbon atoms and r' f is perfluoroalkylene or perfluorooxyalkylene having from 1 to 10 carbon atoms, by reaction of the respective acid fluorides of formulae with fluorine, in the gas phase at 0 to 60°c and in the presence of a catalyst composed of a k, rb, cs or ba fluoride, preferably supported on a material composed of particles of a metal selected from cu, fe, ni and al and arranged in the reactor in the form of a fixed catalytic bed, the process being conducted continuously.
