## Abstract Natural abundance ^17^O NMR data for fifteen 2โ and 4โsubstituted phenols, ten 3โand 5โsubstituted 2โhydroxybenzaldehydes and eight 3โsubstituted benzaldehydes, recorded at 75ยฐC in acetonitrile are reported. The chemical shift change due to intramolecular hydrogen bonding for the phenol
17O, 13C and 1H NMR spectra for paraand meta-substituted 4-arylaminopent-3-en-2-ones (acyclic enaminones, 1 and 2) and 3-arylaminocyclohex-2-en-1-ones (cyclic enaminones, 3 and 4) are reported. The 17O, 13C and 1H shift values of these enaminones correlate well with and constants in the correlations
