Kinetics and Mechanism of Electron Transfer Reactions in Aqueous Solutions: Silver(I) Catalyzed Oxidation of Aspartic Acid by Cerium(IV) in Acid Perchlorate Medium

Article abstract of DOI:10.1002/kin.550270402

Silver(I) catalyzed oxidation of aspartic acid by cerium(IV) was studied in acid perchlorate medium.The stoichiometry of the reaction is represented by the eq. (i), (i) R-CHNH3⁺COOH + 2 Ce(IV) -H2O-> R-CHO + NH4⁺ + CO2 + 2 Ce(III) + 2 H+.Dimeric cerium(IV) species has been indicated and employed in calculations of monomeric cerium(IV) species concentrations.The reaction is second-order and uncatalyzed reaction also simultaneously occurs along with silver(I) catalyzed reaction conforming to the rate law (ii), (ii) , where k is an observed second-order rate constant.A probable reaction mechanism is suggested.
