The complete assignment of the 1H, 13C and 19F NMR spectra of eight Γuoro-substituted 3H-naphthopyrans was achieved by the concerted application of homonuclear (1HΓ1H) and heteronuclear (13CΓ1H and 19FΓ1H) correlations.
The 1 H and 13 C NMR spectra of some 6-substituted 2naphthyl methyl sulphides were assigned unambiguously using NOE and two-dimensional NMR spectral techniques and the influence of substituents on the chemical shifts is discussed.
Selected 1,4-and 1,5-benzoheterazepinones, prepared by the Schmidt rearrangement of flavanone analogues, were converted to the corresponding thiolactam derivatives using phosphorus pentasulfide. The proton and carbon chemical shifts of the thiolactam derivatives are compared with those of their lact
