Abstract
The invention relates to the preparation of perfluoroalkyl bromides or bromoperfluoroalkanes C.sub.n F.sub.2n+1 -Br (n=1 to 20). A perfluoroalkanesulphonyl chloride C.sub.n F.sub.2n+1 -SO.sub.2 Cl is reacted with a compound of formula: ##STR1## in which X represents a nitrogen or phosphorus atom and R.sup.1, R.sup.2, R.sup.3 and R.sup.4, which may be identical or different, each represent an optionally substituted hydrocarbon radical, it also being possible for one of these symbols to be a hydrogen atom.
