  • Oxidation of tryptophan by benzimidazolium dichromate
    S.K. Periyasamy
    Results in Chemistry, 2024
    In order to determine a likely mechanism, tryptophan oxidation with benzimidazolium dichromate (BIDC) in an acid medium utilizing sulfuric acid has been investigated at 313 K. First order dependence is demonstrated by the calculated pseudo-first order rate constant, which is found to be independent of the oxidant’s initial concentration. Additionally, the reaction exhibits first order behavior for both sulfuric acid and tryptophan. The rate of reaction is unaffected by an increase in ionic strength and is lowered by a decrease in the medium’s dielectric constant. Since acrylonitrile is not polymerizing, there is no chance of a free radical mechanism. The two electron transfers involved in the mechanism are confirmed when the concentration of manganous sulphate increases because it slows down the rate of reaction. A suitable mechanism and rate law have been derived from the experimental observations. The oxidation reaction yields carbon dioxide, ammonia, and indole-3-acetaldehyde as its products.
  • Oxidation of thioacids by quinaldinium fluorochromate

    Arabian Journal of Chemistry, 2016
    The kinetics of oxidation of thioglycolic, thiolactic and thiomalic acids by quinaldinium fluorochromate [QnFC] has been studied in non aqueous medium. The oxidation kinetics was followed spectrophotometrically in the temperature range of 30–60 °C. The reaction shows unit order dependence each with respect to substrate and oxidant. The reaction is catalysed by hydrogen ions. The hydrogen ion dependence takes the form kobs = a + b [H+]. The reaction rate decreases with increasing the concentration of Mn2+ ions. The reaction does not induce polymerization of acrylonitrile. A plausible mechanism has been proposed for the formation of a thioester and its decomposition which occur in the slow step.
