Treatment of 2,5-diphenyl-1,4-dithiin-1-oxide with hydrochloric acid in dioxane caused a novel skeletal rearrangement to give 2-benzoyl-4-phenyl-1,3-dithiole together with the deoxygenation products. The reaction with gaseous hydrogen chloride in methanol afforded the adduct due to the additive Pummerer rearrangement, which was also converted into the 1,3-dithiole.
用盐酸在二恶烷中处理 2,5-diphenyl-1,4-dithiin-1-oxide 导致新的骨架重排,生成 2-benzoyl-4-phenyl-1,3-dithiole 和脱氧产物。与气态氯化氢在甲醇中的反应由于加成的普默勒重排而得到加合物,它也被转化为 1,3-二硫醇。
