Abstract

Kinetics of oxidation of aromatic aldehydes by N-chlorosuccinimide (NCS) in the presence of HClO4 and NaCl in aqueous acetic acid medium is reported here. The observed rate of oxidation is first-order with respect to [NCS], [H+] and [CF]. The order with respect to [aldehyde] is always zero. The rate is found to increase with decrease in the dielectric constant of the medium. Increase of ionic strength of the medium decreases the rate of oxidation. Addition of succinimide (>NH), has negligible effect on the rate of oxidation. The product of oxidation is the corresponding acid. Arrhenius and the activation parameters have been calculated. A suitable mechanism is also proposed.
