Thiophene is considered to be aromatic, although theoretical calculations suggest that the degree of aromaticity is less than that of benzene. The "electron pairs" on sulfur are significantly delocalized in the pi electron system. As a consequence of its aromaticity, thiophene does not exhibit the properties seen for conventional sulfides. For ...

Thiophene-2-acetic acid is the organosulfur compound with the formula HO 2 CCH 2 C 4 H 3 S. Together with thiophene-3-acetic acid, it is one of two isomeric thiophene acetic acids. Preparation and use
Thiophene-3-acetic acid is an organosulfur compound with the formula HO 2 CCH 2 C 4 H 3 S. It is a white solid. It is one of two isomers of thiophene acetic acid, the other being thiophene-2-acetic acid. Thiophene-3-acetic acid has attracted attention as a precursor to functionalized derivatives of polythiophene. [1]
Thieno[3,2-b]thiophene. In organic chemistry, thienothiophene is any of several compounds consisting of two fused thiophene rings. They have the molecular formula C 6 H 4 S 2. Three constitutional isomers have been synthesized: thieno[3,2-b]thiophene, thieno[2,3-b]thiophene, and thieno[3,4-b]thiophene. The other isomer features S(IV) and is ...
3,4-Ethylenedioxythiophene (EDOT) is an organosulfur compound with the formula C 2 H 4 O 2 C 4 H 2 S. The molecule consists of thiophene, substituted at the 3 and 4 positions with an ethylene glycolyl unit.
Dibenzothiophene (DBT, diphenylene sulfide) is the organosulfur compound consisting of two benzene rings fused to a central thiophene ring. It has the chemical formula C 12 H 8 S. It is a colourless solid that is chemically somewhat similar to anthracene .
