The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 5-Iodo-2-furaldehyde( cas:2689-65-8 ) is researched.Electric Literature of C5H3IO2.Ballester, L.; Caballero, B.; Fernandez Bertran, J.; Gra, R. published the article 《Study of the first harmonic of the carbonyl stretching vibration of furfural and 5-substituted derivatives》 about this compound( cas:2689-65-8 ) in Revista CENIC, Ciencias Fisicas. Keywords: IR furfural solvent effect; LFER furfural carbonyl stretch. Let’s learn more about this compound (cas:2689-65-8).
The solvent effect on the frequencies of the 1st harmonic of the CO group stretching vibrations in furfural and its 5-NO2, 5-Br, 5-I, 5-Me, or 5-Me2N derivatives was examined The transitions were assigned to the 00 cis and 00 trans rotamers. The 5-substituent affected the CO stretch analogously to the effects of p-substituents on the CO stretch in BzH; the rotamer CO stretching frequencies showed a LFER with σp.
This literature about this compound(2689-65-8)Electric Literature of C5H3IO2has given us a lot of inspiration, and I hope that the research on this compound(5-Iodo-2-furaldehyde) can be further advanced. Maybe we can get more compounds in a similar way.
