Related Products of 271-95-4. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: 1,2-Benzisoxazole, is researched, Molecular C7H5NO, CAS is 271-95-4, about Differentiation between isomeric structures of benzazoles by nitrogen-14, carbon-13, and proton NMR. Author is Stefaniak, Lech.
Isomeric benzazole ring systems were distinguished effectively by N chem. shifts, there being a large difference in N shielding, generally >20 ppm, between isomeric benzenoid- and quinonoid-like structures (for indoles and isoindoles, resp.). 13C and 1H NMR gave unambiguous structure assignment for sym. quinonoid ring systems of azoles.
