Kinetics of Oxidation Deamination and Decarboxylation of DL-Leucine by Acidic Permanganate in presence of Silver Ion

Abstract

The title reaction has been carried out in moderately concentrated

sulphuric acid medium. The reaction is found to be a two stage

process. In both the stages the reaction follows first order behaviour

with respect to each of dL-leucine and permanganate and fractional

with respect to silver ion. Applicability of Zücker Hammett's and

Bünnett's hypotheses exhibits that a water molecule acts as a proton

abstracting agent in the rate determining stage. The activation

parameters have been evaluated and a probable mechanism consistent

with the observed results has been proposed.
