Abstract
Several carbonyl functionalized Z-vinylic tellurides were synthesized. Infr ared spectra of compounds I showed a peculiar pattern. Appreciable shifts t o lower wavenumbers for both the v(C=C) and v(C=O) modes, as well as extens ive mixing of such modes were observed. This behaviour could be rationalize d in terms of a proposed Te-O interaction.
