Abstract

The invention relates to the manufacture of a perfluoroalkyl bromide RFBr by photochemical bromination of the corresponding iodide RFI. In order to obtain a virtually complete conversion of the RFI, its photobromination is carried out in solution in a solvent, the concentration of RFI being no more than 0.5 mol/litre.
