Reaction of 2,4-Dinitrofluorobenzene with o-Anisidine in Benzene. Further Evidence of the “Dimer” Mechanism
The reaction of 2,4-dinitrofluorobenzene with o-anisidine (B) in benzene exhibits a quadratic dependence of the observed second-order rate coefficient, kA, with [B], and similar behavior is found in the reaction with p-anisidine, as was previously reported in the literature. The kinetic results are...

| Sumario: | The reaction of 2,4-dinitrofluorobenzene with o-anisidine (B) in benzene exhibits a quadratic dependence of the observed second-order rate coefficient, kA, with [B], and similar behavior is found in the reaction with p-anisidine, as was previously reported in the literature. The kinetic results are interpreted in terms of a “dimer” nucleophile, B:B, which forms a cyclic intermediate with the substrate. This interpretation is confirmed by the data of the reaction run in the presence of varying amounts of pyridine, where an additional mixed adduct, B:P, is present. © 1983, American Chemical Society.
