Common ether ligands are diethyl ether and tetrahydrofuran. Common chelating ether ligands include the glymes, dimethoxyethane (dme) and diglyme, and the crown ethers. Being lipophilic, metal-ether complexes often exhibit solubility in organic solvents, a property of interest in synthetic chemistry.

It is produced by polymerization of tetrahydrofuran as well as 1,4-butanediol. The product is commercially available as polymers of low average molecular weights , between 250 and 3000 daltons . In this form it is a white waxy solid that melts between 20 and 30 °C.
Deuterated tetrahydrofuran (d 8-THF) is a colourless, organic liquid at standard temperature and pressure. [1] This heterocyclic compound has the chemical formula C 4 D 8 O, and is an isotopologue of tetrahydrofuran. [2] Deuterated THF is used as a solvent in NMR spectroscopy, though its expense can often be prohibitive. [citation needed]
2,2,5,5-tetramethyltetrahydrofuran (TMTHF) or 2,2,5,5-tetramethyloxolane (TMO) is a heterocyclic compound with the formula C 8 H 16 O, or (CH 3) 2 (C(CH 2) 2 OC)(CH 3) 2.It can be seen as derivative of tetrahydrofuran (oxolane) with four methyl groups replacing four hydrogen atoms on each of the carbon atoms in the ring that are adjacent to the oxygen.
2-Methyltetrahydrofuran (2-MeTHF) is an organic compound with the molecular formula C 5 H 10 O. It is a highly flammable, mobile liquid. It is mainly used as a replacement for Tetrahydrofuran (THF) in specialized applications for its better performance, such as to obtain higher reaction temperatures, or easier separations (as, unlike THF, it is not miscible with water).
