Dihydrothiophene is a heterocyclic compound and an organosulfur compound with the formula SC4H6. Two isomers exist, the 2,3-dihydro- (depicted above) and the more symmetrical 2,5-dihydro isomer (CAS# 1708-32-3). Both are colorless liquids with characteristic fragrance of thioethers. In terms of their reactivity, both isomers exhibit characteristics of alkenes and thioethers, undergoing addition reactions at carbon and oxidation at sulfur. In contrast, thiophene engages in neither reaction.[1]
