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...
