WebThiophene synthesis is achieved via a mechanism very similar to the furan synthesis. The initial diketone is converted to a thioketone with a sulfurizing agent, which then undergoes … Reflecting their high stabilities, thiophenes arise from many reactions involving sulfur sources and hydrocarbons, especially unsaturated ones. The first synthesis of thiophene by Meyer, reported the same year that he made his discovery, involves acetylene and elemental sulfur. Thiophenes are classically … See more Thiophene is a heterocyclic compound with the formula C4H4S. Consisting of a planar five-membered ring, it is aromatic as indicated by its extensive substitution reactions. It is a colorless liquid with a benzene-like … See more At room temperature, thiophene is a colorless liquid with a mildly pleasant odor reminiscent of benzene, with which thiophene shares some similarities. The high reactivity of thiophene toward sulfonation is the basis for the separation of thiophene from … See more • Some Thiophenes • Thieno[3,2-b]thiophene, one of the four thienothiophenes. • 2,2'-Bithiophene. • 3,4-Ethylenedioxythiophene (EDOT) is the precursor to commercial antistatic and electrochromic displays. See more Thiophene was discovered as a contaminant in benzene. It was observed that isatin (an indole) forms a blue dye if it is mixed with See more Thiophene is considered to be aromatic, although theoretical calculations suggest that the degree of aromaticity is less than that of benzene.
