Acetylenic αβ-epoxides react with dilute sulphuric acid and mercuric sulphate on heating to give furans in good yields; the reaction involves an internal hydration at a terminal acetylenic carbon atom. Under the influence of sulphuric acid alone, only small quantities of furans are formed; the major products are acetylenicdiols. These have been shown to be probable intermediates in the formation of
