Perfluoroalkanesulfonyl chlorides FSO2Cl; R_F= CF3, C2F5, C4F9>, decompose thermally to give the corresponding perfluoroalkyl chlorides with evolution of SO2.The latter retards the reaction, but it is catalysed by copper which also inhibits the SO2 effect. 2-methyl-2-nitrosopropane traps the perfluoroalkyl free radicals.In the presence of a perfluoroalkyl iodide FI; R'not equal R_F>, other products, R_FI and R_FCl, are obtained.A free radical chain-mechanism is then suggested.On the other hand, perfluorobutanesulfonyl fluoride is very stable thermally.
