“…It is therefore possible to get several reaction constants for different substituents in one of the two rings. The kinetics and mechanism of oxidation of some substituted anils, using several oxidants, have been reported . A literature survey reveals that no report is available on the kinetics of oxidation of meta‐ and parasubstituted aromatic anils with PPMS; hence it is worthwhile to do research on the kinetics and mechanism of oxidation of anils by PPMS.…”

The kinetics of oxidation of aromatic anils to benzaldehyde and azobenzene by potassium peroxymonosulfate has been studied in aqueous acetic acid medium. The low dielectric constant of the medium facilitates the reactivity. It has been found that the variation in the ionic strength of the reaction has a negligible effect on the rate. Similarly, polymerization was not observed when acrylonitrile was added to the reaction mixture. This observation rules out the formation of any free radical in the reaction. The added Mn(II) increases the rate of the reaction, which indicates the involvement of two-electron transfer. Highly negative S # values indicate a structured transition state. The deviation of the Hammett plot was noted, and a concave downward curve was obtained for the anils with substituents in the aniline moiety. The observed break in the log k obs versus σ is attributed to the transition state whereas the concave upward curve was observed for the substituents in the benzaldehyde moiety and in the combination of aniline and benzaldehyde moieties, and a suitable mechanism was proposed.

“…It is possible to evaluate the reaction constant (q) from the Hammett plot by varying substituents in one of the rings X or Y. The kinetics and mechanism of oxidation of some substituted anils, using several oxidants have been reported [7][8][9][10][11][12][13][14]. In this paper, we have mainly ascertained the nature of the transition state.…”

Under identical experimental conditions the kinetics of oxidation of aromatic anils to benzaldehyde and nitrosobenzene, by isonicotinium dichromate, has been studied in aqueous acetic acid medium. The low dielectric constant of the medium facilitates the reactivity. Ionic strength has no significant effect on the conversion. The added Mn(II) decreases the rate of the reaction. The added acrylonitrile has no effect on the reaction rate indicating the absence of free radical mechanism. Highly negative DS # values indicate a structured transition state. The deviation of Hammett plot is noted and a concave downward curve is obtained for the anils with substituents in the aniline moiety. The observed break in the log k obs versus r is attributed to the change in the transition state whereas the linear plot is observed for the substituents in the benzaldehyde moiety. A suitable mechanism has been proposed. Graphical AbstractMechanistic investigation of oxidation of aromatic anils by isonicotinium dichromate in acidic medium. A kinetic study.
