Abstract: Several trichloromethyl sulfones have been subjected to reaction with hydroxide ion in refluxing aqueous tetrahydrofuran in an attempt to elucidate the possible mechanistic pathways involved in the ensuing rearrangement. In particular, sulfones were selected to permit examination of the possible generation and fate of dichloro episulfones and chlorothiirene dioxides. The Ramberg-Backlund rearrangement of trichloromethyl ...
