Stabilization of 2-Pyridyltellurium(II) Derivatives by Oxidorhenium(V) Complexes

open access: yesChemistry, 2023
Zwitterionic compounds such as pyridine-containing tellurenyl compounds are interesting building blocks for heterometallic assemblies. They can act as ambiphilic donor/acceptors as is shown by the products of reactions of the zwitterions HpyTeCl2 or ...

In vitro and in vivo activity of an organic tellurium compound on Leishmania (Leishmania) chagasi. [PDF]

open access: yesPLoS ONE, 2012
Tellurium compounds have shown several biological properties and recently the leishmanicidal effect of one organotellurane was demonstrated. These findings led us to test the effect of the organotellurium compound RF07 on Leishmania (Leishmania) chagasi,

Synthesis, DFT Calculation and Biological Activity of Some Organotellurium Compounds Containing Azomethine Group

open access: yesOrbital: The Electronic Journal of Chemistry, 2019
The reaction of (4-amino-2,3-dichlorophenyl)mercury (II) chloride with 3,4-dihydroxy benzaldehyde produce the organomercury compound 1 in 82% yield. Tellurated of 1 with tellurium (IV) tetrabromide gave the tellurium (IV) tribromide Schiff base compound ...

Xerogel-Sequestered Silanated Organochalcogenide Catalysts for Bromination with Hydrogen Peroxide and Sodium Bromide

open access: yesMolecules, 2015
While H2O2 is a powerful oxidant, decomposing into environmentally benign H2O and O2, a catalyst is often required for reactions with H2O2 to proceed at synthetically useful rates.

Protective effect of the organotelluroxetane RF-07 in pilocarpine-induced status epilepticus

open access: yesNeurobiology of Disease, 2008
Temporal lobe epilepsy is the most common form of epilepsy in humans. Caspase activation is a mechanism of cell death induced by seizures. Tellurium (IV) compounds present antitumoral, immunomodulatory and neuroprotective effects due to their ability to ...

Synthesis and characterization of some new organotellurium compounds based on quinoline [PDF]

open access: yes, 2017
A new series of organotellurium compounds based on quinoline were prepared by the reaction of 8-(quinolyl)mercuric chloride (1) with tellurium tetrabromide in 1:1 and 1:2 mole ratio in dry dioxane to obtain 8-(quinolyl)tellurium tribromide (2) and bis[8-(

Tellurophene‐Induced Triplet–Singlet Spin‐Flip Acceleration: An Advanced Design for Narrowband Organoboron Emitters with Fast Reverse Intersystem Crossing

open access: yesAngewandte Chemie, Volume 138, Issue 14, 27 March 2026.
Linking an auxiliary dibenzo[b,d]tellurophene unit markedly accelerates exciton spin conversion in multi‐resonance‐type thermally activated delayed fluorescence emitters. Owing to the heavy‐atom effect of tellurium, the corresponding OLEDs retain remarkably high external electroluminescence quantum efficiencies exceeding 25% even at an exceptionally ...

Selenium- and Tellurium-Based Antioxidants for Modulating Inflammation and Effects on Osteoblastic Activity

open access: yesAntioxidants, 2017
Increased oxidative stress plays a significant role in the etiology of bone diseases. Heightened levels of H2O2 disrupt bone homeostasis, leading to greater bone resorption than bone formation. Organochalcogen compounds could act as free radical trapping

Synthesis and characterization of carbonyl functionalized organotellurium(iv) derivatives. [PDF]

open access: yesRSC Adv
Aryltellurium trichlorides, ArTeCl3 (Ar = C6H5, Ph; 4-Me-C6H4, p-Tol; 1-C10H7, 1-Nap; 2,4,6-Me3C6H2, Mes) react under mild conditions with acetylacetone/benzoylacetone to give carbonyl functionalized organotellurium(iv ...
