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.Related Products of 2689-65-8.Povazanec, F.; Piklerova, A.; Kovac, J.; Kovac, S. published the article 《Furan derivatives. XLVI. Infrared spectra of substituted 2-furyl cyanides》 about this compound( cas:2689-65-8 ) in Chemicke Zvesti. Keywords: IR furyl cyanide; substituent effect IR furonitrile; solvent effect IR furonitrile. Let’s learn more about this compound (cas:2689-65-8).
The spectral data of the cyanides I (R = H, halo, Me, NO2, AcO) in CHCl3 and CCl4 were given and the influence of substituents and solvents on the wave numbers and integrated absorption intensities of the ν(CN) bands discussed. Wave numbers of the ν(CN) bands increased with increasing electron-acceptor ability of the substituents; the wave numbers were higher than those of the corresponding substituted Ph cyanides. Integrated absorption intensities of the ν(CN) bands decreased with increasing electron-acceptor ability of the substituents and were more significantly influenced by the nature of the substituents and the polarity of the solvents than the wave numbers of these bands.
