摘要

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.
