Cyclic thioacetals and thioketals (1,3-dithiolanes) are reported to react smoothly with halogens in a 1:1 molar ratio, at room temperature in anhydrous carbon tetrachloride.The mechanistic aspects of the reaction are considered and evidence is shown of the itermediacy of monocationic rather than the previously postulated dicatonic species in the cleavage reactions of 1,3-dithiolanes of aromatic ketones.
