Condensation reaction of N-sulphinylperfluoroalkanesulphonamides
Abstract
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 RfSO2NY (Y = CHAr, CR1R2, SR1R2 and PCl3) with elimination of sulphur dioxide.
