syn- and anti-2-Acyl-2-alkyl-1,3-dithiane 1-oxides, when treated with trifluoroacetic anhydride, undergo either an unexpected Pummerer rearrangement or equilibration in near quantitative yield, depending upon the reaction conditions; 2-acyl-1,3-dithiane 1-oxides readily undergo a related rearrangement upon treatment with Lewis acid or exposure to silica gel.
