Reactions of the Difluoramine-Potassium Fluoride Adduct, HNF2∙KF, with Sulfinyl and Perfluoroalkylsulfinyl Fluorides. Preparation of PerfluoroalkylPerfluoroalkylthiosulfonates

Abstract

The reaction of HNF2∙KF, with sulfinyl fluoride gave FS(O)NF2 which was isolated and had sufficient stability to be characterized by spectroscopic methods. Attempts to prepare CF3S(O)NF2 and C2F5S(O)NF2 resulted in the formation of N2F4 and the perfluoroalkyl perfluoroalkylthiosulfonate esters CF3SO2SCF3 and C2F5SO2C2F5. Efforts to synthesize additional thiosulfonate esters led to the characterization of C2F5S(O)Cl, 19F nmr spectral identification of C2F5SO2C2F5 and C2F5SO2C2F5, and spectroscopic characterization of the previously reported C2F5SO2F. © 1973, American Chemical Society.
