31. :The more useful reaction is the disproportionation to water and atomic oxygen, H 2 O 2 ? 32. A subsequent reduction or disproportionation of the substance under the reaction conditions yields a mixture of several methylated arsenic compounds. 33. The " disproportionation " reactions that Benson and Buss refer to are termed loosely as " radical disproportionation " reactions. 34. The " disproportionation " reactions that Benson and Buss refer to are termed loosely as " radical disproportionation " reactions. 35. Although an irreversible capacity loss upon disproportionation of LiO 2 in the charged battery was not addressed in that work. 36. Radicals can undergo disproportionation reaction through radical elimination mechanism ( Figure " Radical disproportionation via radical elimination mechanism " ). 37. Radicals can undergo disproportionation reaction through radical elimination mechanism ( Figure " Radical disproportionation via radical elimination mechanism " ). 38. Fermentation is therefore a type of disproportionation , and does not involve an overall change in oxidation state of the substrate. 39. The radicals are produced by thermal or photochemical reactions, usually from colligation and diffusion, or disproportionation of radical pairs. 40. One can understand this as you must break a ring at more than one site to actually undergo a disproportionation reaction.
