By oxidation of (C2F5S-)(2) (1) with AgF2 at 0 degrees C a mixture of
C2F5SF3 (2) and C2F5SF5 (3) besides C2F5S(O)F (4) is formed. With elem
ental fluorine only 3 is isolated, an intermediate in this reaction is
(C2F5SF4-)(2) (5). At -40 to -30 degrees C the mixture of 2, 3 and 4
was reacted with TASF and AsF5, to give TAS(+) C2F5SF4- (6), TAS(+) C2
F5S(O)F-2(-) (7) and C2F5SF2+AsF6- (8), respectively. While 6 and 7 de
compose rapidly in solution even at low temperatures, of thermally sta
ble 8 the solid state structure was determined by x-ray diffraction.
