Abstract:
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.
