Abstract

Several carbonyl functionalized Z-vinylic tellurides were synthesized. Infrared spectra of compounds 1 showed a peculiar pattern. Appreciable shifts to lower wavenumbers for both the V_C─C and V_C─O modes, as well as extensive mixing of such modes were observed. This behaviour could be rationalized in terms of a proposed Te-O interaction.
