Abstract

Carbon‐13 and proton NMR spectra are reported for phenyl‐,4‐methoxyphenyl‐, 4‐ethoxyphenyl‐ and 3‐methyl‐4‐methoxyphenyltellurium tris(diethyldithiocarbamate). Both the ^1^H and the ^13^C spectra are typical of compounds undergoing a fast exchange process, only the N‐methylene proton signals and the thiocarbonyl carbon signals showing evidence for exchange broadening. The phenyl C‐1 carbon signal is deshielded relative to benzene (by 12.0 ppm), and shows solvent dependence. The thiocarbonyl carbon atoms absorb at 197.5‐199.1 ppm, showing solvent dependence but little sensitivity to the aryl group substituents.

## Abstract Carbon‐13 and proton NMR data of macrocyclic diaromatic dilactones are presented. The observed behaviour of the spectra as a function of temperature shows that the energy barrier for the re‐orientation of the side chains is lower than 49 kJ mol^−1^ (12 kcal mol^−1^) and that the energy
