CHE SIGNIFICA THIOPHEN IN INGLESE
tiofene
Il tiofene, comunemente chiamato tiofurano, è un composto eterociclico con la formula C4H4S. Composto da un anello piatto a cinque elementi, è aromatico come indicato dalle sue estese reazioni di sostituzione. Relative al tiofene sono benzotiofene e dibenzotiofene, contenenti l'anello di tiofene fuso con uno e due anelli di benzene rispettivamente. I composti analoghi al tiofene includono furano e pirrol.
