SYNTHESIS, MECHANISTIC INTERPRETATION AND KINETIC APPROACH OF m-TOLUIC ACID HYDRAZIDE BY THALLIUM(III) IN ACIDIC MEDIUM

摘要

The reaction between thallium(III) and m-toluic acid hydrazide is carried out in a mixture of perchloric and hydrochloric acid medium. The reaction proceeds through formation of complex with reactant, which decomposes in subsequent steps to give product. Effect of acrylonitrile shows, that there is no formation of free radicals. The increase in [H+] and [Cl-] decreases the rate of the reaction. The increase in ionic strength does not affect the rate of reaction. The effect of temperature was studied at four different temperatures ranging from 15 to 30 degrees C. The activation parameters were also determined and a mechanism is predicted.
