Kada, Rudolf; Ilavasky, Dusan; Goljer, Igor; Gaher, Peter published an article about the compound: 5-Iodo-2-furaldehyde( cas:2689-65-8,SMILESS:IC1=CC=C(O1)C=O ).Computed Properties of C5H3IO2. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:2689-65-8) through the article.
2-Cyanomethylbenzothiazole reacts with 3-(5-substituted 2-furyl)-, 3-(2-thienyl)- or 3-(2-pyrrolyl)-2-cyanoacrylonitrile in THF under catalysis of triethylamine to give 1-(2-benzothiazolyl)-1-acyano-2-heteroarylethylenes e.g. I (R = H, X = O, S, NH; R = Br, Me, NO2, X = O) as a result of replacement of malonodinitrile by 2-cyanomethylbenzothiazole.
