The oxidation of pyridine-2-aldehyde (2-PyA) by benzimidazolium fluorochromate (BIFC) has been studied in aqueous acetic acid medium. The oxidation leads to the formation of the pyridine-2-carboxylic acid. The reaction is first order with respect to [BIFC], [2-PyA] and [H + ] and the reaction is catalyzed by hydrogen ions. The reaction mixture failed to induce the polymerization of added acrylonitrile. The reaction has been studied in different percentage of acetic acid-water mixture. The decrease in dielectric constant of the medium increases the rate of the reaction or low dielectric constant of the medium favours the reactivity. A suitable mechanism has been proposed.

“…Quinolinium chlorochromate 14 is a stable reagent originally introduced as an oxidizing agent for alcohol is used in synthetic organic chemistry [15][16][17][18][19][20] . The kinetic mechanistic aspects of oxidation reactions by QCC reports are available in the literature [21][22][23][24][25][26] The kinetics of oxidation of Phenols by various oxidizing reagents have been well studied 27-29 . Phenol is so inexpensive that it attracts many small-scale uses. It once was widely used as an antiseptic, especially as carbolic soap.…”

ABSTRACT. The kinetics of Oxidation of Phenol and aniline by quinolinium Chlorochromate (QCC) in aqueous acetic acid medium leads to the formation of quinone and azobenzene respectively. The reactions are first order with respect to both Phenol and aniline. The reaction is first order with respect to quinolinium chlorochromate(QCC) and is catalyzed by hydrogen ion. The hydrogen-ion dependence has the form:The rate of oxidation decreases with increasing dielectric constant of solvent, indicating the presence of an ion-dipole interaction. The reaction does not induced the polymerization of acrylonitrile. The retardation of the rate by the addition of Mn 2+ ions confirms that a two electron transfer process is involved in the reaction. The reaction rates have been determined at different temperatures and the activation parameters have been calculated. From the above observations kinetic results a probable mechanism have been proposed.

Electron-transfer processes in micellar systems can be considered as models to get insight into electron-transport occurring in biological phenomena. It has been established that arrangement of hydroxy groups in polyhydroxylic molecules affects the oxidation rate of chromium (VI). There have been only a limited number of studies of chromium (VI) redox reactions in surfactant media. Therefore we have made systematic studies of the oxidative degradation of surfactants by different oxidant metal-ions. Kinetic studies are expected to provide information on how
