✦ Synopsis

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 confirm earlier conclusions based upon other physical methods and indicate that C-13 NMR should prove useful in studies of such interactions.
