INFLUENCE OF SUBSTITUENTS ON THE MECHANISM OF OXIDATION OF AMINO-ACIDS

[摘要] The kinetics of oxidation of amino acids (AA) by peroxomonosulphate in aqueous alkaline medium at 35 degrees C is studied. Based on the experimental results, a reaction scheme is proposed in which the electrophilic attack of HSO5- occurs at the amino nitrogen. The break down of the intermediate is influenced by the nature of the substitutents at the amino carbon atom. The formation of imine/imino acid is supported by the absorption spectra of the intermediate.
