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.Lauzardo, N.; Mocelo, R.; Padron, G.; Buttner, J.; Fanghaner, F. published the article 《Comparative study by mass spectrometry of the fragmentation of 5-substituted furfurals》 about this compound( cas:2689-65-8 ) in Ciencias, Serie 3: Quimica. Keywords: furfural fragmentation mass spectra; methylfurfural fragmentation pathway; chlorofurfural fragmentation pathway; bromofurfural fragmentation pathway; iodofurfural fragmentation pathway; nitrofurfural fragmentation pathway; carbomethoxyfurfural fragmentation pathway; carboxyfurfural fragmentation pathway; substituent furfural mass spectra. Let’s learn more about this compound (cas:2689-65-8).
A comparative study on the fragmentation of a series of 5-substituted furfurals (X = H, CH3, Cl, Br, I, NO2, COOCH3, COOH) was made. Depending on the nature of the substituent, 2 main pathways of fragmentation were observed One of them starts with the fragmentation of the aldehyde group (X = H, CH3, Cl, Br, I). The other starts with the fragmentation of substituents (X = NO2, COOCH3, COOH). The spectra are discussed on the basis of these 2 fragmentation pathways.
