The detailed mechanism of the Dushman reaction explored by computer

Since 1926 investigations of the Dushman reaction have relied mainly upon “constant-rate” measurements, usually by instrumental methods. Since about that time, the confusion surrounding this venerable reaction has been growing. In part, the confusion arises because the reaction involves reactive intermediate species that have not been studied directly—and may never be. Alternative detailed mechanisms have been assumed with little restraint. One of these, which is built around H₂I₂O₃, has been explored by computer with promising results. The mechanism seems capable of reducing the confusion now attending the Dushman reaction and others related to it.
