1H and 13C NMR study of substituted 3-OH pyridines
nJHH, nJCH and δ13C values have been measured for a series of X substituted 3-hydroxypyridines (X = 2-NH2, 2-NO2, 5-Cl, 6-CH3, 2-Cl, 2-Br, 2-I). The results show that the additivity of δ13C provides a valuable criterion to differentiate the phenolic from the zwitterion structure. This conclusion is...
