Synthesis and application of organotellurium compounds

Physical Sciences Reviews, 2022
Abstract Organotellurium compounds define the compounds containing carbon (organic group) and tellurium bond (C–Te). The first organic compound containing tellurium was prepared by Wohler in 1840 after the discovery of the metal by the Austrian chemist F. J. Muller von Reichenstein in the year 1782.

Stabilization of PACREL by organotellurium compound

Journal of Applied Polymer Science, 1998
The addition of 0.17-0.50% of bis[4-(dimethylamino)phenyl] telluride to the thermoplastic elastomer PACREL(R) significantly improved tensile strength and elongation at break in unaged and oven-aged ...

Stabilisation of PVC with organotellurium compounds

Polymer Degradation and Stability, 1988
Abstract Organotellurium compounds are shown to behave similarly to organotin compounds as thermal and UV stabilisers for PVC. The most effective of these, the dialkyltellurium maleates, were, however, less effective than the corresponding tin compounds but the study points the way to further progress in the design of organometallic compounds as PVC ...

Improved antioxidant formulations for polymeric materials—synergistic protective effects in combinations of organotellurium compounds with conventional phenolic antioxidants or thiols

Polymer Degradation and Stability, 2003
As judged by differential scanning calorimetry experiments at 190 °C and chemiluminescence measurements at 150 °C, addition of 0.10–0.30 wt.% of certain organotellurium compounds to polypropylene caused a notable protection against oxidation of the ...

Thermodynamics of organoselenium and organotellurium compounds

Russian Chemical Reviews, 1995
Experimental values of the enthalpies of formation (ΔHf°) and of the specific heat (Cp°) of the organic compounds of selenium and tellurium, are discussed, including their complexes with dialkylzinc and dialkylcadmium. Different forms of the methods of combustion enthalpy and of reaction calorimetry, used to determine ΔHf° values, are examined.

Antioxidative properties of organotellurium compounds in cell systems

Biochemical Pharmacology, 1998
The protective/antioxidative properties of diaryl tellurides were demonstrated in cellular systems of increasing complexity. In the presence of glutathione, bis(4-hydroxyphenyl) telluride (1a), bis(4-aminophenyl) telluride (1d) and bis(2-carboxyphenyl) telluride (1h) reduced by more than 50% t-butyl hydroperoxide-induced cell death in lung fibroblast ...

ANTIBACTERIAL PROPERTIES OF ORGANOTELLURIUM COMPOUNDS

Problems of Biological, Medical and Pharmaceutical Chemistry
Introduction. Antimicrobial resistance in bacteria has become a global challenge for public health systems. Bacteria that pose the greatest threat to human health due to their increasing resistance to antibiotics include Escherichia coli, Staphylococcus aureus and Salmonella spp. The purpose of the work is to study the antibacterial properties of three

Specific features of the reactivity of organotellurium compounds

Russian Chemical Reviews, 1995
The characteristic features of the reactivity of the principal classes of organic compounds of tellurium(II) and tellurium(IV) are examined and compared with the analogous compounds of sulfur and selenium. The factors determing the specific features of the chemical behaviour of orgamotellurium compounds are characterised.
