Information on the scope and limitations of the "Ramberg-Bäcklund" approach to episulfone synthesis is provided. Several α-halothiane 1,1-dioxides have been converted into the corresponding isolable episulphones, but attempts to extend this procedure to related α-halo-thiepane, thiolane and thietane dioxides were unsuccessful. The first example of an acyclic episulphone to be prepared by the Ramberg-Bäcklund route is described.
