Description:
Thiophene is five-member heterocyclic compounds containing a sulfur atom and is presented at coal tar crude benzene at small amounts. It is a kind of colorless liquid having similar order as benzene aromatic with the boiling point being 84℃. It is insoluble in water, and can be mixed with ethanol, ethyl ether, acetone, benzene, carbon tetrachloride, heptane, pyridine, and 1,4-dioxane. It is flammable, and has a high heat resistance without being decomposed when being heated to 850℃. It is not polymerized under acidic conditions, nor does it be decomposed and be susceptible to oxidation. It also has moderate toxicity. The 5 atoms in thiophene ring belong to sp2 hybrid and located in the same plane. The occupied p-orbital of a pair of non-sharing electrons in the sulfur atom is parallel and overlapped with that of occupies the 4 carbon atoms which form 5 atoms/6 electrons closing conjugated system and thus having aromaticity. Thiophene is more prone to have electrophilic substitution reaction than benzene with electrophilic substitution mainly occurring in alpha- position (2-position or 5-position). An important derivative of thiophene is biotin which can have sulfonation reaction with concentrated sulfuric acid at room temperature with producing 2-thiophene acid which can be dissolved in sulfuric acid.
