Review of Chemical Kinetics in Oxidation Reactions Involving Thallium (III) and Polymer-Supported Chromium (VI) in Acidic Media

Abstract : The results of multiple kinetic and mechanistic studies on the oxidation of alcohols and hydrazides using polymer-supported chromium(VI) and thorium(III) in acidic conditions are summarized in this study. These investigations reveal the underlying reaction orders, thermodynamic parameters, mechanistic routes, and variables such as pH, solvent polarity, dielectric constant, and chloride concentration. Cr(VI)-supported systems function with zero-order kinetics, whereas Tl(III)-mediated oxidations follow non-radical routes, including the creation of intermediate complexes. The paper emphasizes the importance of precisely manipulating reaction parameters in providing valuable insights into the chemical kinetics of redox systems, utilizing polymer-supported chromium (VI) and thorium (III) in acidic conditions, which are summarized.
