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.
