Synthesis of N-perfluoroalkanesulfonyl aromatic imines

N-Sulfinyl perfluoroalkanesulfonamides, RfSO2NSO, prepared by refluxing perfluoroalkanesulfonamides with thionyl chloride, react easily with aromatic aldehydes giving N-perfluoroalkanesulfonyl aromatic imines, RfSO2N=CHAr, through elimination of sulfur dioxide.

Condensation Reaction of N-Sulphinylperfluoroalkanesulphonamides

N-Sulphinylperfluoroalkanesulphonamides, RfSO2NSO, which are prepared by refluxing of perfluoroalkanesulphonamides with thionyl chloride, react easily with aldehydes, ketones, sulphoxides and phosphorus trichloride oxide yielding a series of new compounds RfSO2=Y (Y = CHAr, CR1R2, SR1R2 and PCl3) with elimination of sulphur dioxide.
