Kinetics and mechanism of oxidation of glycine by iron(III)–1,10- phenanthroline complex in perchloric acid medium

Kinetics and mechanism of oxidation of glycine by iron(III)–1,10-phenanthroline complex has been studied in perchloric acid medium. The reaction is first order with respect to iron(III) and glycine. An increase in (phenanthroline) increases the rate, while increase in [H+] decreases the rate. Hence it can be inferred that the reactive species of the substrate is the zwitterionic form and that of the oxidant is [Fe(phen)2(H2O)2]3+. The proposed mechanism leads to the rate law as elucidated.
