Die Desulfonierung–Fluorierung von Thiuramdisulfiden, [R2NC(S)S]2 und Silberdithiocarbamaten, Ag[SC(S)NR2] (R = CH3, CH3CH2, C6H5CH2), mit Silber(I)fluorid, AgF — ein einfacher Zugang zu Diorgano(trifluormethyl)aminen, R2NCF3, und Thiocarbamoylfluoriden,

AgF and [R2NC(S)S]2 (R = CH3, CH3CH2, C6H5CH2), selectively react at room temperature in the stoichiometric ratio of 1:1 to give the corresponding N,N-diorganothiocarbamoyl fluorides, R2NC(S)F, AgSC(S)NR2 and elemental sulfur. Under comparable conditions in a ratio >3:1 both reactants selectively yield diorgano(trifluoromethyl)amines, R2NCF3, AgSC(S)NR2, Ag2S and elemental sulfur. At stoichiometry 6:1, R2NCF3, Ag2S besides elemental sulfur are formed. By analogy, thiocarbamoyl fluorides and silver dithiocarbamates react with AgF yielding selectively the corresponding trifluoromethylamines.
