1. DMSO is metabolized by disproportionation to dimethyl sulfide and dimethyl sulfone. 2. The enzyme can also be assayed via disproportionation of ETF semiquinone. 3. This disproportionation reaction is catalysed by methanogen archaea in their fermentative metabolism. 4. In this reaction, chlorine undergoes disproportionation , both reduction and oxidation. 5. Formerly the reaction had been called " olefin disproportionation ." 6. Hydrogen peroxide is then formed from the disproportionation of the superoxide anion. 7. There are several aspects of the disproportionation mechanism that are still unclear. 8. In solution methylborane is more stable against disproportionation than dimethylborane. 9. Such compounds are susceptible to disproportionation reactions and are not stable in water. 10. That will speed up the disproportionation reaction without contaminating it with some catalyst.
