Popis:	Sa151H and 13C NMR spectra were measured for a series of synthetic substituted 1-bromo-2-aryloxyethanes and monosubstituted xanthones. Substituent effects were analysed and compared with those of the respective 3-aryloxypropiononitriles with the same substitution pattern. Spectral assignments were made on the basis of comparisons of coupled and 1H-decoupled 13C spectra and DEPT experiments. Two-dimensional homonuclear 1H–1H and heteronuclear 1H–13C techniques (COSYDQF and XHCORRDC) were used for unequivocal signal assignments.
