Abstract
The oxidation of 2,3-diaminopropionic acid (APA) by diperiodatocuprate(III) was studied spectrophotometrically between 298.2 K and 313.2 K in alkaline medium. The oxidation rate law was obtained : kobs = 2kK1[OH–][APA]/(K1[OH–] + [H2IO62–]). A reaction mechanism including a pre-equilibrium step was proposed. Activation parameters and the rate constants of the rate-determining step are calculated.
