SYNTHESIS OF PERFLUOROALKYL BROMIDES

摘要

The preparation of perfluoroalkyl bromides or bromo- perfluoroalkanes CnF2n+1 or insert-Br (n = 1 to 20). …Gaseous hydrogen bromide is reacted with a perfluoroalkanesulphonyl chloride CnF2n+1SO2Cl in the presence of a catalyst consisting of a tertiary amine or phosphine or of a quaternary ammonium or phosphonium salt at a temperature ranging from 80 to 200 DEG C.
