Synthesis and Characterization of New Organotellurium (IV) Compounds Containing Carbodithioate Ligands

IOP Conference Series: Materials Science and Engineering, 2020
A series of organotellurium(IV) dithiocarbomate compounds have been synthesized in good yields under mild reaction conditions by reacting sodium telluromorpholine-4-carbodithioate and disodium homopiperazine-1,4-bis-carbothionate with various ...

Diphenyl Ditelluride Intoxication Triggers Histological Changes in Liver, Kidney, and Lung of Mice

Analytical Cellular Pathology, 2015
Tellurium compounds may be cytotoxic to different cells types. Thus, this work evaluated the effect of diphenyl ditelluride ((PhTe)2), an organotellurium commonly used in organic synthesis, on the morphology of liver, kidney, and lung.

New Radical Coupling Reactions with Organotellurium Compounds.

Journal of Synthetic Organic Chemistry, Japan, 2002
Organotellurium compounds reversibly generate carbon-centered radicals upon photolysis and thermolysis, and the radicals thus generated can be used for carbon-carbon bond formation with a variety of radical acceptors. For example, a variety of organotellurium compounds react with quinones to give the corresponding adducts, including polyprenyl ...

The Role of Chalcogen Bonding in Organic Dichalcogenides of Biological Interest

Chemistry – An Asian Journal, Volume 20, Issue 10, May 15, 2025.
Experimental and theoretical studies consistently show that selenium and tellurium in dichalcogenides compounds can function as efficient chalcogen bond (ChB) donors. Their electrophilic behavior may suggest that the formation of a ChB could represent the preliminary step of the molecular mechanism resulting in the anti‐redox activity of ...

Ochrobactrum sp. MPV1 from a dump of roasted pyrites can be exploited as bacterial catalyst for the biogenesis of selenium and tellurium nanoparticles [PDF]

, 2017
Background: Bacteria have developed different mechanisms for the transformation of metalloid oxyanions to non-toxic chemical forms. A number of bacterial isolates so far obtained in axenic culture has shown the ability to bioreduce selenite and tellurite

Kumada‐Tamao Catalyst‐Transfer Condensation Polymerization of AB2 Monomer: Synthesis of Well‐Defined Hyperbranched Poly(thienylene‐phenylene)

Macromolecular Rapid Communications, Volume 46, Issue 9, May 2025.
Kumada‐Tamao catalyst‐transfer condensation polymerization of AB2 monomer in the presence of Ni(dppe)Cl2 in THF affords hyperbranched poly(thienylene‐phenylene) with a narrow molecular weight distribution and controlled molecular weight, which is close to the theoretical molecular weight calculated from the ratio of consumed AB2 monomer to Ni(dppe)Cl2.
