METHOD FOR PREPARING MX+[-N(CF3)2]X IMINO SALT AND ITS APPLYING Russian patent published in 2005 - IPC

FIELD: chemistry of metalloorganic compounds.

SUBSTANCE: invention relates to the improved method for preparing imino salt of the formula M^x+[^-N(CF₃)₂]_x that is a source of anions N(CH₃)₂ and the following replacing halide or other groups in organic molecules with the group N(CH₃)₂. Method involves interaction of metal fluoride of the general formula MF_x wherein M is Na, K, Rb, Cs, Ag, Cu, Hg; x = 1 or 2 under condition that x = 1 if M means Na, K, Rb, Cs or Ag, and x = 2 if M represents Cu or Hg with sulfonamide of the general formula: R_fSO₂N(CF₃)₂ wherein R_f means F or C_nF_2n+1; n = 1-4, or with sulfonamide of the general formula (CF₃)₂N(SO₂CF₂)_mSO₂N(CF₃)₂ wherein m = 0, 1 or with N,N-bis-(trifluoromethyl)perfluoroacylamide of the general formula: R_fCON(CF₃)₂ in polar organic solvent medium to obtain the corresponding solutions containing imino salts of the general formula M^x+[^-N(CF₃)₂]_x and, respectively, sulfonylfluorides of the general formula R_fSO₂F, and sulfonyldifluorides of the general formula: F(SO₂CF₂)_mSO₂F of salt of the general formula: R_fCF₂O^-M⁺. Also, invention relates to applying imino salts of the general formula M^x+[^-N(CF₃)₂]_x and [bis-(trifluoromethyl)imido]rubidium as a reagent for replacing halogen or other groups in organic molecules with the group N(CF₃)₂.

EFFECT: improved preparing method.
