Product Details of 2689-65-8. 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. Compound: 5-Iodo-2-furaldehyde, is researched, Molecular C5H3IO2, CAS is 2689-65-8, about 3-(5-X-2-Furyl)-2-cyanoacrylonitriles on reaction with 2-cyanomethylbenzothiazole.
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.
