✦ Synopsis

The kinetics of permanganate oxidation of L-phenylalanine in acid medium at a constant ionic strength has been investigated spectrophotometrically. An autocatalytic reaction was observed being autocatalyzed by a soluble form of Mn(1V).

The reaction appears to involve a parallel consecutive reaction process in which Mn(1V) is formed as an intermediate and Mn(I1) as a reaction product. A tentative mechanism consistent with the kinetics is discussed.
