Comparative Kinetic and Mechanistic Study of Oxidation of Benzoic, o-toluic Benzoic, p-Toluic Benzoic acid Hydrazides with Thallium (III) in Acidic Medium

摘要

The kinetics and Mechanism of oxidation of benzoic, o- Toluic benzoic and p- Toluic benzoic acid hydrazides by thallium(III) in acidic is carried out iodometrically by keeping ionic strength of reaction mixture constant.The reaction proceeds through formation of complex with reactant, which decomposes in subsequent steps to give product. The increase in [H~+] and [Cl~-] decreases the rate of the reaction. The thermodynamic parameters were also determined and a mechanism is predicted.
