Trifluoromethylnitro compound is prepared in a high yield from an alkali salt and a cationic trialkyl or triaryl salt. Compound of formula (I): (((R<1)<CR<2>R<3>)k)lAxKt)<+>N(CF3)2 (I) Kt = N, P, As, Sb, S or Se; A = N, P, P(O), O, S, S(O), SO2, As, As(O), Sb or Sb(O); R<1> - R<3> = H, halogen, CnH2n+1, 1-18C alkenyl, 1-18C alkynyl, CmH2m-1, phenyl or heteroaryl; n = 1-18; m = 3-7; k = 0-6; l = 1 or 2 when x = 1 and 1 when x = 0; x = 0 or 1; and y = 1-4. An Independent claim is included for the preparation of the above compound by reacting an alkali salt of formula (II) with a salt of formula (III) in an organic polar solvent: D<+>N(CF3)2 (II) (((R<1)<CR<2>R<3>)k)lAxKt)<+>E (III) D = alkali metal; and E = F, Cl, Br, I, BF4, ClO4, AsF6, SbF6 or PF6. |
