Llinares, Jeanine; Galy, Jean Pierre; Faure, Robert; Vincent, Emile Jean; Elguero, Jose published the article 《Structure and reactivity of benzoxazoles: carbon-13 nuclear magnetic resonance study》. Keywords: benzoxazole structure reactivity NMR; oxazole structure reactivity NMR; aminophenol structure NMR; phenol amino structure NMR; substituent oxazole derivative NMR.They researched the compound: 2-Ethylbenzo[d]oxazole( cas:6797-13-3 ).Quality Control of 2-Ethylbenzo[d]oxazole. 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:6797-13-3) here.
Thirty-four benzoxazoles, oxazole, and 10 o-aminophenols were studied by 13C NMR spectroscopy. All the signals are attributed to substituent effects. The structures of the products obtained by the nitration of benzoxazole were determined by 13C NMR. The shifts induced by substitution at the 2 position are discussed as a function of an empirical model by using the structural parameters F, R, and Q*. Azido-tetrazole equilibrium (N3 in position 2) and prototropic tautomerism (NH2, OH, and SH in position 2) are also discussed. The chem. shifts and coupling constants of oxazole and unsubstituted benzoxazole are compared.
In some applications, this compound(6797-13-3)Quality Control of 2-Ethylbenzo[d]oxazole is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
