FIELD: organic chemistry, chemical technology.
SUBSTANCE: invention relates to new compounds of the general formula: {[R1]yKt}+-N(CF3)2 (I) representing stable salts used as precursors of organic compounds. In the formula (I) Kt means nitrogen atom (N), phosphorus atom (P); R1 means similar or different values and each means unsubstituted or substituted with phenyl (CnH2n+1)-alkyl, unsubstituted phenyl; groups bound with Kt can be similar or different and wherein n = 1-18; y = 4 with exception for (C2H5)4N+ -N(CF3)2. Also, invention relates to a method for preparing these compounds wherein compound of the formula: D+-N(CF3)2 (II) wherein D is taken among group including alkaline metals, or compound of the formula: GN(CF3)2 (IV) wherein G represents fluorinated sulfonamides are subjected for interaction with salt of the general formula: {[R1]yKt}+-E (III) in polar organic solvent and wherein -E means F-, Cl-, Br-, J-, BF- 4, ClO- 4, AsF- 6, SbF- 6 or PF- 6.
EFFECT: improved method for preparing.
