(57) [Summary] [Structure] General formula [Chemical formula 1] (Rf 1 and Rf 2 are C 1 to C 5 perfluoroalkyl groups, both of which may be bonded directly or via O or N to form a heterocycle), and a nitrogen-containing perfluoroalkyl bromide General formula A method for producing the perfluoroalkyl bromide by decarbonylating a nitrogen-containing perfluorocarboxylic acid bromide represented by (Rf 1 and Rf 2 have the same meanings as described above) under UV irradiation. [Effect] A nitrogen-containing perfluoroalkyl bromide useful as a synthetic intermediate, a fire extinguishing agent, a flame-retardant additive, an X-ray contrast agent, etc. can be obtained in a high yield by a simple operation from easily available raw materials. |
