Abstract
With the preparation of C2F5(F)C=Te, the third, non-resonance stabilis ed perfluorinated telluracarbonyl has been isolated and characterised by mass spectrometry. It was prepared via pyrolysis of the novel compo und Me3SnTe(n-C3F7) at 550 degrees C, 10(-3) Torr in 45% yield. The co mpound C2F5(F)C=Te is only stable at -196 degrees C and dimerises quan titatively a few degrees above this temperature to the corresponding m ixture of (pentafluoroethyl)-2,4-difluoro-1,3-ditelluretane.
