The title system produces oscillations only when it is catalyzed by both Mn2+ and [Fe(phen)3]2+. Mn2+ catalyzes the oxidation of alanine to produce pyruvic acid, while [Fe(phen)3]2+ is the real catalyst in the pyruvic acid oscillating reaction. The effects of temperature on the oscillation were also studied and the activation energies calculated The effects of other factors on the oscillations were also studied. The oscillations are controlled by both Br- and Br2. Thus, the oscillating mechanism is the same as that of the Br2 hydrolysis model.
