Povazanec, F.; Piklerova, A.; Kovac, J.; Kovac, S. published the article 《Furan derivatives. XLVI. Infrared spectra of substituted 2-furyl cyanides》. Keywords: IR furyl cyanide; substituent effect IR furonitrile; solvent effect IR furonitrile.They researched the compound: 5-Iodo-2-furaldehyde( cas:2689-65-8 ).Quality Control of 5-Iodo-2-furaldehyde. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:2689-65-8) here.
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.
After consulting a lot of data, we found that this compound(2689-65-8)Quality Control of 5-Iodo-2-furaldehyde can be used in many types of reactions. And in most cases, this compound has more advantages.
