Abstract
The interesting behavior of the Briggs–Raucher oscillating reaction does not stop with the end of oscillations. Depending on the initial concentrations, the classic mixture with malonic acid may undergo a sudden transition from a state with low [I2] and [I−], to a state with high [I2] and [I−]. A proposed mechanism involving radical attack on iodomalonic acid and diiodomalonic acid shows qualitative agreement with experiments.
