✦ Synopsis

The stoichiometry and kinetics of the oxidation of ethylenediaminetetraacetate by [Fe(phen)3] 3 +, [Fe(bipy)3] 3 + and [ComW12040] 5-were studied in aqueous HC10 a. Reaction rates were first order with respect to the oxidants and the reductant, and the dependence of the second order rate constant k2 on [H + ] is given by k2 = a + b[H+] -1.

The primary products were CO2, CH20 and (CHzNH2) 2. Schuster treatment is employed to show that the reactions occur by the outersphere mechanism.
