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

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).

Convenient methods for the synthesis organotellurium compounds derived from pyrazole derivatives: synthesis and antimicrobial evaluation

Phosphorus Sulfur and Silicon and the Related Elements, 2022
A new series of organic tellurium compounds containing pyrazole derivatives were prepared. Initially, penta-2,4-dione-3-tellurocyanate (1) was prepared by the refluxing equimolar amounts of potassium tellurocyanate with 3-chloro-2,4-pentadione.
