So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Marchalin, Stefan; Mamani, Lucy Nieves Hinojosa; Ilavsky, Dusan; Pronayova, Nada; Lesko, Jan researched the compound: 5-Iodo-2-furaldehyde( cas:2689-65-8 ).Formula: C5H3IO2.They published the article 《Synthesis and spectral properties of 2-(5-R-2-furylmethylene)-3-oxobutanenitriles》 about this compound( cas:2689-65-8 ) in Collection of Czechoslovak Chemical Communications. Keywords: furylmethyleneoxobutanenitrile; butanenitrile furylmethylene; condensation furaldehyde aminobutenenitrile; substituent effect conjugation furylethylene system; LFER furylmethyleneoxobutanenitrile; structure property furylmethyleneoxobutanenitrile. We’ll tell you more about this compound (cas:2689-65-8).
Substituted 2-(5-R-2-furylmethylene)-3-oxobutanenitriles I (R = H, halo, Ph, etc.) were obtained by condensation of the corresponding 5-R-2-furaldehydes II with 3-amino-2-butenenitrile in acid medium. Relation between the structure and spectral properties (NMR, IR, UV, MS) is presented and the influence of substituents in position 5 of the furan ring on the conjugated 2-furylethylene system is discussed.
In addition to the literature in the link below, there is a lot of literature about this compound(5-Iodo-2-furaldehyde)Formula: C5H3IO2, illustrating the importance and wide applicability of this compound(2689-65-8).
