Non-stereospecific ring expansion reactions of 5-membered heterocyclic sulfoxides, 1,3-benzoxathiole sulfoxides, 1,3-benzodithiole sulfoxides, and 1,3-dithiolane sulfoxides having a heteroatom at β-position to the sulfinyl group with acetic anhydride or p-toluenesulfonic acid are described together with their reaction mechanism involving a sulfonium ion intermediate.
