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 ...
As a consequence, thiophene exhibits few properties expected for a sulfide – thiophene is non-nucleophilic at sulfur and, in fact, is sweet-smelling. Upon hydrogenation , thiophene gives tetrahydrothiophene , C 4 H 8 S, which indeed does behave as a typical sulfide.
A carbocation mechanism is inferred from the structure of 3-(4-octylphenyl)thiophene prepared from ferric chloride. [33] Polymerization of thiophene can be effected by a solution of ferric chloride in acetonitrile. The kinetics of thiophene polymerization also seemed to contradict the predictions of the radical polymerization mechanism. [63]
Heterocyclic organic chemistry is the branch of organic chemistry dealing with the synthesis, properties, and applications of organic heterocycles. [2] Examples of heterocyclic compounds include all of the nucleic acids, the majority of drugs, most biomass (cellulose and related materials), and many natural and synthetic dyes. More than half of ...
Since most conductive polymers require oxidative doping, the properties of the resulting state are crucial. Such materials are salt-like (polymer salt), which makes them less soluble in organic solvents and water and hence harder to process. Furthermore, the charged organic backbone is often unstable towards atmospheric moisture.
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 ...
Benzo[c]thiophene is an organic compound with the chemical formula C 8 H 6 S. [1] The similarly named Benzo[b]thiophene is an isomer with the sulfur in the position adjacent to the benzene ring. Benzo[b]thiophene is more stable and far more commonly encountered.
Thiophenol is an organosulfur compound with the formula C 6 H 5 SH, sometimes abbreviated as PhSH. This foul-smelling colorless liquid is the simplest aromatic thiol.The chemical structures of thiophenol and its derivatives are analogous to phenols, where the oxygen atom in the hydroxyl group (-OH) bonded to the aromatic ring in phenol is replaced by a sulfur atom.
