ABSTRACT:
The oxidative decarboxylation of the glycine by N-bromobenzimidazole (BBI) has been studied in aqueous acetic acid medium. The rate shows first order dependence each on [BBI] and [glycine] and inverse fractional order on [H+]. The rate of the oxidation increases with decrease in dielectric constant of solvent medium indicating ion-dipole interaction. The rate of reaction is not influenced by the addition of electrolyte like sodium perchlorate. Polymerization was not observed when acrylonitrile is added to the reaction mixture. The kinetic runs were carried out at four different temperatures and thermodynamic parameters have been evaluated. Addition of benzimidazole retards the rate. A mechanism in consistent with the kinetic data has been proposed.
