Perfluoro (tetramethylene)sulphilimine and its N-chloro- and N-bromoderivatives. Perfluoro(tetramethylene)sulphoximine and its N-chloro-derivative
Abstract
Perfluoro(tetramethylene)sulphur difluoride is a useful precursor to the new perfluoro-cyclic sulphilimines [graphic omitted]NX (X = H, Cl, or Br) and perfluoro-cyclic sulphoximines [graphic omitted](O)= NX (X = H or Cl).
