The 17O shift values of para-substituted benzoyl compounds (X = H, COOEt, Br, Cl, F, p-YC 6 H 4 COX CF 3 , SEt, OCOAr, OH, O-Na', were measured. The 17O shielding values d(17O) of these and other aryl-NH 2 ) unsubstituted benzoyl compounds (Y = H) follow the electron-donating power of X (resonance),

The 54.2 MHz I7O NMR spectra of a series of naturally occurring coumarins and furocoumarins and those of a number of related model compounds are described. The ''0 chemical shifts of the furocoumarins can be predicted by the evaluation of the data of substructures in model compounds. syn-Periplanar
The 17O chemical shifts of substituted benzyl ethers and a set of organotin(IV) derivatives containing O,C,O-chelating ligands were studied. Measured 17O chemical shifts were correlated with the additivity substituent increments for carbon atoms in the alkyl groups, and intramolecular Sn-O distance
