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.

THERMOLYSE DES ANHYDRIDES PERFLUOROALCANESULFONIQUES. MECANISME ET APPLICATION A LA SYNTHESE DES ESTERS RFSO3RF.

Perfluoroalkanesulfonic anhydrides FSO2)2O ; RF=CF3,C2F5,C4F9>, mixed with the parent acid, decompose thermally to give the corresponding perfluoroalkyl perfluoroalkanesulfonates (RFSO3RF) with liberation of SO2.If the perfluoroalkyl moieties in the anhydride and the acid are different, a mixture of symmetric and unsymmetric esters is obrained.An ionic bimolecular mechanism is deduced from the results, and a new easy synthesis of the symmetric perfluorinated sulfonic esters is proposed.

OXYDATION ANODIQUE DE IODOPERFLUOROALCANES DANS LES ACIDES PERFLUOROALCANESULFONIQUES. PREPARATION DE NOUVEAUX ESTERS SULFONIQUES TOTALEMENT FLUORES RFSO3R'F A LONGUES CHAINES

Perfluorinated sulphonic esters RFSO3R'F and fluorosulphates FSO3R'F, are easily obtained by anodic oxidation of iodoperfluoroalkanes R'FI in perfluoroalkene sulphonic acids RFSO3H (RF=CF3, C2F5, C4F9) and fluorosulphuric acid.With di-iodo compound I(CF2)4I, the mono and the diester can be selectively obtained.The alkaline hydrolysis of these esters produces perfluorinated carboxylic compounds.Polyfluorinated iodide R'FCH2CH2I are also oxidized in similar conditions.The mechanism of the electrolytic reaction is discussed.
