Dihydrothiophenes are heterocyclic organosulfur compounds. Two isomers are possible for the parent C4H6S:[1]
- 2,3-Dihydrothiophene, a vinyl thioether. CAS RN = 1120-59-8.
- 2,5-Dihydrothiophene, an allylic thioether. A well-known derivative is 2,5-dihydrothiophene 1,1-dioxide. CAS RN = 1708-32-3.
Chemical structures of 2,3-dihydrothiophene (left) and 2,5-dihydrothiophene (right)
Depending on the substituents, some dihydrothiophenes are called 4,5-dihydrothiophenes.
