Perfluoroalkyl perfluoroalkanesulfonates RFSO3R'F (RF, R'F = CF3, C2F5) and perfluoroalkyl perfluoroalkanepyrosulfonates RFSO3SO3RF, mixed with perfluoroalkanesulfonic acids (CF3SO3H or C2F5SO3H) decompose thermally.Depending on the starting materials, different products result from nucleophilic attack of a perfluoroalkanesulfonate anion of the acid on the sulfur atom of the sulfonate group of the ester, with heterolysis of the S-O bond.Therefore, under these conditions, the perfluorinated esters are not perfloroalkylating agents, but rather perfluorosulfonylating agents.
