General description

Tetrahydrofuran (THF) is a saturated cyclic ether mainly used as an organic solvent. On long term storage it forms organic peroxides. This process can be suppressed by adding butylated hydroxytoluene (BHT) as a stabilizer. BHT removes the free radicals required for the peroxide formation. It constitutes the key fragment of various natural products (polyether antibiotics). THF forms double hydrate with hydrogen sulfide, crystal structure of this double hydrate has been investigated by three-dimensional single-crystal studies.

Application

Dry tetrahydrofuran (THF) has been used in the synthesis of dichloro{bis[1,1′,1′′-(phosphinetriyl)tripiperidine]}palladium [(P(NC5H10)3)2Pd(Cl)2], which is widely used in the Heck reaction as a catalyst. It has been employed in the reaction medium of the Heck cross-coupling reaction of various aryl bromides and olefins.

Other Notes

Greener alternatives are available for many THF applications, 2-Methyltetrahydrofuran (414247) and Cyclopentyl methyl ether (675970)
