The 19F NMR chemical shifts of individual diethylamine and dibutylamine monohydrofluorides in chloroform are 32-33 ppm (on the trifluoroacetic acid scale).The stability of secondary amine monohydrofluorides in organic media is well above that of the corresponding tertiary compounds (the difference in equilibrium constants is as much as three orders of magnitude).The stability of amine monohydrofluorides in solution is determined by the energy and number of intra-and intermolecular hydrogen bonds of the fluoride ion and falls with rise in temperature.
Chemistry of trifluoromethylsulfinyl fluoride. Trifluoromethylsulfinamides and trifluoromethylsulfinate esters

Trifluoromethylsulfinate esters and trifluoromethylsulfinamides result when trifluoromethylsulfinyl fluoride reacts with alcohols and amines. Mercaptans with CF3S(O)F do not yield the expected thiosulfinates but rather mixed disulfides. The methylene protons of CF3CH2OS(O)CF3 and CH3CH2OS(O)CF3 are magnetically nonequivalent giving rise to ABM3X3 nmr spectra. The new compounds CF3S(O)OCH3, CF3S(O)OCH2CH3, CF3S(O)OCH2CF3, CF3S(O)N(CH2CH3)2, CF3S(O)N(CH3)2, (CF3S(O))2NCH3, and CF3S(O)NH2 are slightly volatile, colorless liquids.
