摘要

With the synthesis of CF3 (F) CTe, the second, non-resonance stabilised perfluorinated telluracarbonyl has been isolated and characterised by gas-phase IR and mass spectrometry. It was prepared via pyrolysis of the novel compound Me3SnTeC2F5 at 500° C, 10–3 Torr in 40–50% yield. The compound CF3 (F) CTe is only stable at–196° C and dimerises quantitatively a few degrees above this temperature to the corresponding ...
