Abstract

Kinetics and mechanism of oxidation Or L-methionine by iron(III)-1,10-phenanthroline complex have been studied in perchloric acid medium. The reaction is first order each in iron(III) and methionine. Increase in [phenanthroline] increases the rate while increase in [HClO4] decreases it. While the reactive species of the substrate is the zwitterionic form, that of the oxidant is [Fe(phen)(2)(H2O)(2)](3+). The proposed mechanism leads to the rate lawd[Fe(phen)(3)(2+)]/dt = k(2)K(4)K(3)K(2)(2)[Fe-III][phen](2)[Met]/(1 + K-1[H+])([H+](2) + K4K3K22[phen](2)).
