REACTION OF TETRAKIS(DIMETHYLAMINO)ETHYLENE WITH CF2Br2 IN THE PRESENCE OF SECONDARY AMINES, FORMATION OF N-TRIFLUOROMETHYL-DIALKYLAMINES
N-trifluoromethylamines of the general formula 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 secondary amines R2NH with the reagent combination tetrakis(dimethylamino)ethylene/CF2Br2/(CH2)4SO2 in moderate yields.The new N-trifluoromethylamines have been characterized by elemental analyses, multinuclear NMR and vibrational spectra and the mechanism of formation is discussed.
