R. Juschke et al., SYNTHESES AND STRUCTURE OF POTASSIUM-4,4- IFLUORO-[1,3,2]DITHIAZETIDINIDE-1,1,3,3-TETRAOXIDE AND AFLUORO-[1,3,2]DITHIAZOLIDINIDE-1,1,3,3-TETRAOXIDE, Zeitschrift fur Naturforschung. B, A journal of chemical sciences, 52(3), 1997, pp. 359-366
Reactions of perfluoroalkane-1,n-bis(sulfonylfluorides) (n = 1-2) (1-2
) with liquid ammonia in tetrahydrofuran (THF) lead to the cyclic ammo
nium imides 3-4. These cyclic imides 3-4 can easily be transformed to
other salts using the corresponding hydroxides. X-ray structure analys
es (T = 150 K) were performed for the potassium ifluoro-[1,3,2]dithiaz
etidinide-1,1,3,3-tetraoxide 5 and afluoro-[1,3,2]dithiazetidinide-1,1
,3,3-tetraoxide 6. Cylic imides of the type 3, 5 have not been reporte
d previously. Their formation and their nmr-data are discussed.
