  Diaryl Tellurium Dihalides: From Te-Tetracoordinated Compounds to Te-Tricoordinated Molecular Complexes

  摘要：

  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.

  Aerobic Photooxidation of Phosphite Esters Using Diorganotelluride Catalysts

  摘要：

  Diorganotellurides containing bulky aromatic substituents are found to catalyze the photooxidation of phosphite esters using aerobic oxygen as a terminal oxidant. A Hammett plot with substituted triaryl phosphites yielding rho = 2.88 agrees with a nucleophilic oxygen transfer from telluroxide to phosphite.

  This paper reports an efficient method for the epoxidation of a variety of functionalized olefins using diaryltellurium dicarboxylates as hypervalent tellurium compounds. This method is able to efficiently convert olefins into epoxides using catalytic amounts of tellurium and urea hydrogen peroxide. Furthermore, we propose that this reaction proceeds via the formation of peroxides of phenol, carboxylic
