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

摘要

The invention relates to the preparation of an RF Br perfluoroalkyl bromide by photochemical bromination of the corresponding iodide RF I in solution in an inert solvent. Bromination is initiated by the homolytic cleavage of the C-I bond of the compound RF I, in the presence of bromine. For this purpose, a particular radiation lamp such as a XeCl * or I2 * excimer lamp is used. / P
