Kinetic studies on permanganate oxidation of acetophenones under phase transfer catalysis

Abstract

Kinetic studies on the permanganate oxidation of acetophenone and some of its substituents in organic media using the techn1que of phase transfer catalysis are reported. Tricaprylmethylammonium chloride and tetrabutylammonium bromide have been used as the phase transfer catalysts. The reaction shows first order dependence each on [ketones] and the

[permanganate ions] respectively. The rate coefficients fit well with the Hammett equation and the ρ-value calculated agrees well with the reaction requirements.
