Il tetraidrofurano (nome IUPAC: ossolano ), noto anche come THF, è un etere ciclico ed è anche il prodotto di completa idrogenazione del furano. Il suo analogo a catena aperta è l'etere dietilico. Il suo omologo a sei termini è il tetraidropirano, l'analogo a quattro termini è l'ossetano. Un dietere ciclico ad esso accostabile come solvente è il diossano.

Tetrahydrofuran (THF), or oxolane, is an organic compound with the formula (CH2)4O. The compound is classified as heterocyclic compound, specifically a cyclic ether. It is a colorless, water-miscible organic liquid with low viscosity. It is mainly used as a precursor to polymers. Being polar and having a wide … See more About 200,000 tonnes of tetrahydrofuran are produced annually. The most widely used industrial process involves the acid-catalyzed dehydration of 1,4-butanediol. Ashland/ISP is one of the biggest producers of this … See more THF is a Lewis base that bonds to a variety of Lewis acids such as I2, phenols, triethylaluminum and bis(hexafluoroacetylacetonato)copper(II). THF has been … See more Tetrahydrofurans The tetrahydrofuran ring is found in diverse natural products including lignans, acetogenins, and polyketide natural products. Diverse methodology has been developed for the synthesis of substituted THFs. See more • Loudon, G. Mark (2002). Organic Chemistry (4th ed.). New York: Oxford University Press. p. 318.
