Abstract
The kinetics of oxidation a few cyclanols (cyclopropanol, cyclobutanol, cyclopentanol, cyclohexanol and cycloheptanol) by 1-bromobenzimidazole (BBI) has been studied in 80% acetic acid - water (v/v) medium in presence of mercuric acetate. The reaction exhibits first order rate dependence each with respect to [BBI], [cyclanols] and [H+]. The rates of the reactions increase with increase in acetic acid content of the solvent medium. The variation of ionic strength has no significant effect on the reaction rate. The reaction does not induce any polymerization with acrylonitrile. The addition of benzimidazole has no appreciable effect on the reaction rate. The reactions were studied at different temperatures and the thermodynamic parameters were calculated. A plausible mechanism and an appropriate rate law have been deduced for the observed kinetic data
