Abstract
The Arrhenius parameters for the reactions of 3-fluoro-4-nitro-, 4-fluoro-3-nitro-, 3-fluoro-5-nitro-, and 2-fluoro-4-nitro-NN-dimethylaniline N-oxides and 4-fluoro-3-nitro-, and 3-fluoro-5-nitro-phenyltrimethylammonium chlorides with methoxide ion in absolute methanol have been determined. The results are consistent with the operation of a small π-inductive effect and give the relative activating sequences m-+NMe3 > m-NO2 > m-+NMe2O– and p-NO2 > p-+NMe3 > p-+NMe2O– in aromatic nucleophilic replacement reactions.
