Iran Manuscript received 11 December 2006, accepted 14 February 2007 Tetramethylammonium fluorochromate (TMAFC) oxidation of para-substituted aniline. in varying mole fractions of benzene in 2-methylpropan-2-ol, in the presence of p-toluenesulfonic acid (PTS) i. first-order in TMAFC and PTS and is zero-order with respect to substrate. The TMAFC oxidation of six para-substituted anilines at 298-308 K complies with the isokinetic relationship but not to any of the linear free energy relationships; the isokinetic temperature lies within the experimental range. The specific rate of oxidizing specics-anilines reaction correlates with Brown-Okamoto's substituent constant~ affording negative reaction constant. The correlation of rate data with macroscopic solvent parameters such as ɛr and ETN is satisfactory while correlation with Kamlet-Taft's solvatochromic parameters (α,β, π*) suggests that the specific solute-soh tnt interactions play a major role in governing the reactivity.
