Résumé :

NMR spectra of 10 aza-aromatic derivatives have been recorded at 60 Mc in CCl4. The following effects have been observed: deshielding or ortho, para, peri and "angular" protons and shielding of meta protons. The deshielding of H12 (H-α4 type) in naphto[2,1-h]quinoline is exceptionally strong (-672,5 c/s. T.M.S. = 0). Attention is drawn to the fact that the result of this work could be used to solve many structural problems resulting from ambiguous syntheses (Skraup and related reactions). © 1964.
