Notes:
The utility of C-13 NMR in detecting transannular interactions of a carbonyl group with —O—, —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 confirm earlier conclusions based upon other physical methods and indicate that C-13 NMR should prove useful in studies of such interactions.
