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 utility of C-13 NMR in detecting transannular interactions of a carbonyl group with 4-, -S-and -N-in eight-membered ring compounds has been studied. The C-13 carbonyl chemical shifts were determined in two solvents, employing frequency-sweep and pulse/Fourier transform techniques. The results co
