|Section2= |Section3= }} In chemistry, 2,2,5,5-tetramethyltetrahydrofuran or 2,2,5,5-tetramethyloxolane is a heterocyclic compound with the formula , or (CH3)2(C(CH2)2OC)(CH3)2. It can be seen as derivative of tetrahydrofuran (oxolane) with two methyl groups replacing two hydrogen atoms on each of the carbon atoms in the ring that are adjacent to the oxygen. It can be seen also as a cyclic ether of 2,5-dimethylhexane, an isomer of octane. It is sometimes denoted by the abbreviations TMTHF or Me4THF. The compound is sometimes used as a polar aprotic solvent in research chemistry〔Alan S. Goldman, Jack Halpern (1987) ''Novel catalytic chemistry of iridium polyhydride complexes''. Journal of the American Chemical Society, volume 109, issue 24, pages 7537–7539. 〕〔Parveen Kaushal and Brian P. Roberts (1989), ''Cyclisation of ω-(isocyanatocarbonyl)alkyl radicals: acyclic precursors of imidyl radicals''. Journal of the Chemical Society, Perkin Transactions 2, issue 10, pages 1559–1568. 〕 and as a reagent in chemical synthesis.〔 ==Natural occurrence== The compound is produced in small quantities by the mycelium of ''Tuber borchii'', a mushroom similar to the truffle.〔Bruno Tirillini, Giorgio Verdelli, Francesco Paolocci, Paolo Ciccioli, Massimiliano Frattoni (2000)''The volatile organic compounds from the mycelium of ''Tuber borchii ''Vitt.''.
