Furan is a heterocyclic organic compound, consisting of a five-membered aromatic ring with four carbon atoms and one oxygen atom. Chemical compounds containing such rings are also referred to as furans. Furan is a colorless, flammable, highly volatile liquid with a boiling point close to room temperature.
The compound exists as a hydride-bridged dimer, which easily cleaves in the presence of reducible substrates. [1] 9-BBN is also known by its nickname 'banana borane'. [2] This is because rather than drawing out the full structure, chemists often simply draw a banana shape with the bridging boron. [3] [better source needed]
2,5-Dihydrofuran is an organic compound classified as a monounsaturated derivative of furan. It is a colorless, volatile liquid. It is a colorless, volatile liquid. It can be produced from the acid-catalyzed rearrangement 1‑butene 3,4‑epoxide .
Dibenzofuran is a heterocyclic organic compound with the chemical structure shown at right. It is an aromatic compound that has two benzene rings fused to a central furan ring. All the numbered carbon atoms have a hydrogen atom bonded to each of them. It is a volatile white solid that is soluble in nonpolar organic solvents.
2,5-Dimethylfuran is a heterocyclic compound with the formula (CH 3) 2 C 4 H 2 O. Although often abbreviated DMF, it should not be confused with dimethylformamide. A derivative of furan, this simple compound is a potential biofuel, being derivable from cellulose.
Benzofuran is the heterocyclic compound consisting of fused benzene and furan rings. This colourless liquid is a component of coal tar. Benzofuran is the structural nucleus (parent compound) of many related compounds with more complex structures. For example, psoralen is a benzofuran derivative that occurs in several plants.
2,3-Dihydrofurans are intermediates in the Feist–Benary synthesis of furans from α-halogen ketones and β-dicarbonyl compounds. [4] The 2,3-dihydrofuran ring can be synthesized by several methods. These routes usually involve cyclization or cycloaddition reactions of carbonyl compounds using metal-containing catalysts.
