THE THERMAL CLEAVAGE OF BORON TRIS-TRIFLUOROMETHANESULFONATE (TRIFLATE) AND BORON TRIS-PENTAFLUOROETHANESULFONATE (PENTFLATE) TO TRIFLIC (PENTFLIC) ANHYDRIDE AND TRIFLUOROMETHYL TRIFLATE (PENTAFLUOROETHYL PENTFLATE)

Cleavage of boron tris-trifluoromethanesulfonate(triflate) and boron tris-pentafluoroethanesulfonate(pentflate) was studied at 200 degC.Complete cleavage giving boron trifluoride, sulfur dioxide, carbonyl fluoride (trifluoroacetyl fluoride), triflic (pentflic) anhydride, triflic (pentflic) triflate (pentflate) and boric acid was observed.A mechanism for the cleavage based on formation of the identified compounds is suggested.
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.
