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.Zelikman, Z. I.; Kul’nevich, V. G. researched the compound: 5-Iodo-2-furaldehyde( cas:2689-65-8 ).Product Details of 2689-65-8.They published the article 《Catalytic synthesis of furan 1,3-dioxanes and study of their properties》 about this compound( cas:2689-65-8 ) in Geterogen. Kataliz Reakts. Poluch. Prevrashch. Geterotsikl. Soedin.. Keywords: furan acetal dioxane; kinetics furfural polyol condensation. We’ll tell you more about this compound (cas:2689-65-8).
Cyclic furan acetals of the 1,3-dioxane type were prepared by reaction of furfural, 5-substituted furfurals, furylacrolein, furfurylidenacetone, or 2-acetylfuran with polyols (trimethylolpropanol, trimethylolethanol, and pentaerythritol dichlorohydrin) at 100° in the presence of KU-2 cation exchange catalyst. The kinetics of the reaction was studied. The reaction obeyed a 1st order equation and occurred by the formation of a protonated complex with aldehyde, sorption on the catalyst surface, followed by accelerated nucleophilic attack by the alc. mol. Reaction of a protonated complex with alc. mol. was a limiting chem. reaction stage. The acetylation reaction stage of 5-substituted furfurals increased in the order of substituents Me < H < Cl < Br < iodine < NO2. The furyl 1,3-dioxanes exist in 2 stereoisomeric forms.
