Category: naphthyridine. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: 5-Iodo-2-furaldehyde, is researched, Molecular C5H3IO2, CAS is 2689-65-8, about Study of the nucleophilic substitution of halogens in furan compounds. (I). Furfurals. Author is Mocelo, R.; Pustovarov, V..
5-Bromofurfural (I, R = Br) was prepared by treating I (R = H) in dichloroethane with Br in the presence of hydroquinone. Reaction of I (R = Br) with LiCl in DMF gave 74% I (R = Cl) and with KI-HOAc gave 80% I (R = I). I (R = I) was similarly obtained in 44% yield from I (R = Cl). I (R = Cl) could also be converted to I (R = Br) with KBr-HOAc.
