2,3-Dihydrofuran
2,3-Dihydrofuran is a heterocyclic compound with the formula . It is isomeric with 2,5-dihydrofuran. 2,3-Dihydrofuran is one of the simplest enol ethers. It is a colorless volatile liquid. Reactions It undergoes lithiation upon treatment with butyl lithium. The resulting 2-lithio derivative is a versatile intermediate. Synthesis and occurrence 2,3-Dihydrofurans are intermediates in the Feist–Benary synthesis of furans from α-halogen ketones and β-dicarbonyl compounds. 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. Iodine can also serve as a catalyst as well as Raney nickel Raney nickel , also called spongy nickel, is a fine-grained solid composed mostly of nickel derived from a nickel–aluminium alloy. Several grades are known, of which most are gray solids. Some are pyrophoric, but most are used as air-stable s .... References ...
