The generation and reactivity of N-halo compounds and their importance in biological systems have been reviewed1. The aqueous solution of halogen has a strong oxidizing character. The species responsible for such oxidizing character may be different depending on the pH of the medium2-3. Although a lot of works have been reported on the oxidation of organic compounds by N-halo compounds4-7 it is to be noted that no systematic kinetic investigation on the oxidation of 3-benzoylpropionic acid by N-bromoacetamide has yet been reported in the literature. Here we report the results of the kinetics of the oxidation of 3-benzoylpropionic acid (KA) with N-bromoacetamide (NBA) in aqueous acetic acid medium in the presence of perchloric acid.
