  摘要：

  Rate constants of reactions between sodium salts of diarylamines N-anions and hexafluorobenzene and pentafluoropyridine in DMSO at 25 degreesC were determined. The Bronsted factors for substrates under consideration are 0.14 and 0.34 respectively. These data evidence a considerable effect of substrate electrophilicity on the reactivity of diarylamines N-anions in the SNAr reactions. Deviations of the Bronsted plot from linearity for the reactions of hexafluorobenzene with aryl-and diarylamines N-anions may be due to the difference in internal barriers of these reactions.

  A good correlation has been established between the Bronsted coefficients beta(Nuc) and beta(ox) for reactions of aryl-containing N-anions with various aryl halides. This correlation reflects the dependence of the internal barrier of aromatic nucleophilic substitution on the oxidation potentials of nucleophiles.
