REACTIVITE DES ESTERS SULFONIQUES ET PYROSULFONIQUES PERFLUORES RFSO3RF ET RFSO3SO3RF. HETEROLYSE DE LA LIAION S-O

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.
THERMAL STABILITY OF PERFLUOROALKANESULFONIC ACIDS AND THEIR ANHYDRIDES. NEW AND EASY APPROACH TO RFSO2ORF ESTERS.
Hassani, M. Oudrhiri,Germain, A.,Brunel, D.,Commeyras, A.
, p. 65 - 68 (2007/10/02)
Perfluoroalkanesulfonic anhydrides (RFSO2)2O when mixed with acids decompose into perfluoroalkanesulfonic esters RFSO2ORF, thereby providing a new facile synthesis of these esters from perfluoroalkanesulfonic acids and phosphorus pentoxide.
