Sa151H and 13 C 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 1 H‐decoupled 13 C spectra and DEPT experiments. Two‐dimensional homonuclear 1 H– 1 H and heteronuclear 1 H– 13 C techniques (COSYDQF and XHCORRDC) were used for unequivocal signal assignments.
