11. Thus, piperidine and tetrahydrofuran are conventional amines and ethers, with modified steric profiles. 12. It is commercially available as the white solid trihydrate and as a solution in tetrahydrofuran . 13. It is commercially available as a solution in diethyl ether or tetrahydrofuran ( THF ). 14. Samarium ( II ) bromide will reduce ketones in tetrahydrofuran if an activator is absent. 15. Oxidation with iodine in tetrahydrofuran gives the borane tetrahydrofuran complex, which can reduce carboxylic acids. 16. Oxidation with iodine in tetrahydrofuran gives the borane tetrahydrofuran complex, which can reduce carboxylic acids. 17. The absolute ethanol, sparingly soluble in methanol, and freely soluble in acetone and tetrahydrofuran . 18. It is a white tetrahydrofuran ( THF ), but not in diethyl ether or hydrocarbons. 19. Indicating its diminished aromaticity relative to benzene, furfural is readily hydrogenated to the corresponding tetrahydrofuran derivatives. 20. It is also a component along with tetrahydrofuran of the solvent used to weld plumbing.
