Thiophene is a naturally occurring substance found in coal tar and petroleum. It is also produced industrially for use as an organic synthesis reagent and may be released to the environment through a variety of waste streams.

Thiophene, the simplest sulfur-containing aromatic compound, with molecular formula C4H4S, which closely resembles benzene in its chemical and physical properties. It occurs with benzene in coal tar, from which source it was first isolated in 1883.

Thiophene being an electron-rich heterocycle is directly chlorinated with chlorine gas either in acetic acid or carbon tetrachloride yielding a mixture of polychlorinated products. Chlorination of thiophene with sulfuryl chloride gives a mixture of 2-chloro- and 2,5-dichlorothiophenes.

Thiophene is a heterocyclic compound of particular interest in the field of organic chemistry. This cyclic molecule, sometimes referred to as thiofuran, consists of four carbon atoms and one sulfur atom in a ring structure.

2024年4月22日 · Thiophene is a liquid with a boiling point of 84 °C, found in coal tar. It occurs as a contaminant of benzene, when obtained from coal tar. fig-01. Thiophene is an electron-rich aromatic compound. Its resonance energy is approximately equal to that of pyrrole, and much higher than that of furan. It is found in nature in certain plant products ...
