reportActive / Technical Report | Accession Number: ADA048074 | Open PDF

Abstract:

An improved synthesis of CF3SF3 has been devised which involves the direct fluorination of CF3SSCF3 in a continuous flow reactor. C13 and variable temperature F19 NMR data have been acquired for CF3SF3. These data indicate that the CF3 group occupies an equatorial site on a idealized trigonal bipyramidal structure. The barrier to intramolecular fluorine exchange in CF3SF3 is unusually high 17 kcalmole.
