Synthesis of a bromide perfluoroalkyl iodide by bromination photochemical of the corresponding.

摘要

The invention relates to the preparation of a perfluoroalkyl bromides rf br by bromination photochemical of the corresponding rf (i) in solution in an inert solvent. & br / the bromination is initiated by the homolytic scission of the connection c - i of the compound r.sub.f i, in the presence of bromine. For this purpose, it is used for a particular radiation, such as a lamp of the excimer xecl.sup. * * or i2
