  31P- and 125Te-NMR spectroscopy. Acyclic compounds with C˭P-Te moieties are in general thermally labile, but bulky substituents enhance the lifetime of a number of species. The P-chlorophosphaalkene (Me3Si)2C˭PCl (1a) reacts with the disilyltelluride (iPrMe2Si)2Te (2) leading to the mixed-substituted telluride (Me3Si)2C˭PTeSiMe2iPr 3a which reacts with another equivalent of 1a furnishing the tellurobis(phosphaalkene)

• Sterically hindered thiolato, selenolato and tellurolato complexes of mercury(II)
  作者：Manfred Bochmann、Kevin J. Webb

  DOI：10.1039/dt9910002325

  日期：——

  Mercury(II) complexes of sterically demanding arenechalcogenolato ligands, Hg(EC6H2R3-2,4,6)2 (E = S or Se; R = Me, Pr(i) or Bu(t): E = Te; R = Me or Pr(i)) have been prepared. Whereas complexes carrying smaller aryl substituents (R = Me) are polymeric, those with R = Pr(i) and Bu(t) form linear two-co-ordinate molecules. For a given R, the volatility of the complexes increases for E = S < Se < Te, while the thermal stability decreases in the same sequence. The preferred thermal decomposition pathway is reductive elimination to metallic mercury and the corresponding diaryl dichalcogenide. The oxidative addition of diaryl ditellurides to mercury and the reverse reaction are dependent on solvent polarity and steric factors; in the case of Te this leads to an unexpected decrease in stability with increased steric hindrance of the aryl substituents, R = Me > Pr(i) >> Bu(t).

• Diaryl Tellurium Dihalides: From <i>Te</i>-Tetracoordinated Compounds to <i>Te</i>-Tricoordinated Molecular Complexes

  X-ray structural studies demonstrate that diaryl tellurium diiodides can be constrained by steric factors (ortho-alk.yl substituents) to adopt a trigonal pyramidal structure in preference to the expected bisphenoidal structure. DFT calculations are shown to reproduce successfully structural details of the title compounds; they allow one to predict which coordination number should be energetically favored. All compounds are chiral, but the barrier to stereomutation by intra- and intermolecular pathways (60-85 kJmol(-1)) is rather low.
