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.

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 ...

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.

Controlled Radical Polymerization of Ethylene Using Organotellurium Compounds

Angewandte Chemie International Edition, 2017
AbstractThe first successfully controlled radical polymerization (CRP) of ethylene is reported using several organotellurium chain‐transfer agents (CTAs) under mild conditions (70 °C, 200 bar of ethylene) within the concept of organotellurium‐mediated radical polymerization (TERP).

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

Organotellurium compounds as stabilizers for polymeric materials

Journal of Applied Polymer Science, 1996
The thermal stability of a series of organotellurium compounds was determined by thermogravimetric analysis and the stabilizing capacity of the most heat-resistant compounds assessed in natural rubber, polyethylene, and polypropylene by measurement of ...

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.
