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

A 125Te Mössbauer Study of Organotellurium Compounds

1976
The investigation of tellurium compounds using the Mossbauer effect for 125Te is of some interest since such experiments allow a comparison with similar studies of compounds of tin and antimony. In the past much of the work on 125Te has been primarily concerned with the halides and oxides of tellurium.

Microwave-Assisted Group-Transfer Cyclization of Organotellurium Compounds

The Journal of Organic Chemistry, 2004
Primary- and secondary-alkyl aryl tellurides, prepared by arenetellurolate ring-opening of epoxides/ O-allylation, were found to undergo rapid (3-10 min) group-transfer cyclization to afford tetrahydrofuran derivatives in 60-74% yield when heated in a microwave cavity at 250 degrees C in ethylene glycol or at 180 degrees C in water. To go to completion,

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).

Organotellurium compounds as efficient retarders of lipid peroxidation in methanol

Free Radical Biology and Medicine, 1995
Diaryl tellurides were found efficiently to retard azo-initiated lipid peroxidation of linoleic acid in methanol. The most efficient compounds, 31 and 39, contained one and two hydroxyl groups, respectively, in the para positions and methyl groups in all four positions ortho to tellurium.

Assessment of Organotellurium Compounds for Use as Movpe Precursors

MRS Proceedings, 1988
ABSTRACTIn order to reduce the growth temperature of (Hg,Cd)Te by MOVPE below 350–400°C, alternative organometallic precursors will be required which either decompose at a lower temperature than existing precursors or which absorb strongly at a suitable wavelength in the ultraviolet.

Organotellurium Compounds 8. Aryltellurols as Reducing Agents

Synthetic Communications, 1984
Abstract Phenyltellurol and 2-thienyltellurol, generated in situ, have been found to act as selective reductants towards a number of representative organic substrates.

A Mössbauer study of organotellurium compounds. Part I

Canadian Journal of Chemistry, 1976
Mössbauer data for a wide range of organotellurium compounds are reported, including compounds of the type: R2Te, Ar2Te, Ar2Te2, R2TeX2, Ar2TeX2, and ArTeX3; where R = alkyl, Ar = aryl, and X = Cl, Br, or I. The isomer shifts and quadrupole splittings are interpreted in terms of the relative populations of the tellurium 5s and 5p orbitals.

Screening of organotellurium compounds for use as MOVPE precursors

Journal of Crystal Growth, 1991
Abstract This paper reports an effective screening and characterization proceedure for MOVPE precursors and presents results on recently exploited organotellurium compounds. Central to the studies are detailed and accurate vapour pressure measurements.
