HUO, SHUYING et al. KINETICS AND MECHANISM OF OXIDATION OF 6-AMINOCAPROIC ACID BY DIHYDROXYDIPERIODATOA RGENTATE (III) IN ALKALINE MEDIUM. J. Chil. Chem. Soc. [online]. 2007, vol.52, n.1, pp. 1102-1105. ISSN 0717-9707.  doi: 10.4067/S0717-97072007000100011.

The oxidation of 6-Aminocaproic acid by Ag(III) complex, dihydroxydiperiodatoargentate(III) (DPA), was studied in alkaline medium. The reaction was first order with respect to Ag(III) complex, and the order with respect to 6-aminocaproic acid was from one to two. A plausible mechanism involving a pre-equilibrium of adduct formation between the complex and reductant was proposed form the kinetics study. The rate equations derived from mechanism can explain all experimental phenomena, and the activation parameters along with rate constants of the rate-determining step were calculated
