R2NCF3 (R= Me (I),Et (II), i-Pr (III), i-Bu (IV); 2R = (CH3)2C-(CH2)3-C(CH3)2 (V) and(CH2)6 (VI) ) have been obtained from the corresponding secondaryamines R2NH with the reagent combination tetrakis(dimethylamino)ethylene/CF2Br2/(CH2)4SO2in moderate yields. The new N-trifluoromethylamineshave been characterized by elemental analyses, multi-nuclearNMR and vibrational spectra and the mechanism of formationis
