Abstract:

Iodometric analysis is used to determine the kinetics and mechanism of oxidation of benzoic, m-amino, and m-nitro benzoic acid hydrazides by Thallium(III) in acidic medium at constant ionic strength. The complex decomposes to produce the product. The rate of the reaction is decreased by the rise in [H+] and [Cl-]. Additionally, Activation parameters were established, and a mechanism is proposed. The analysis of reaction constants (ρ) and substituent constants (σ) for m-nitro BAH and m-amino BAH indicates good agreement with the values from the literature.
