A glimpse on biological activities of tellurium compounds

Anais da Academia Brasileira de Ciências, 2009
Tellurium is a rare element which has been regarded as a toxic, non-essential trace element and its biological role is not clearly established to date. Besides of that, the biological effects of elemental tellurium and some of its inorganic and organic ...

Maleic Anhydride and Its Derivatives: A Brief Review of Reactivity and Properties in Radical (Co)Polymerizations. [PDF]

Macromol Rapid Commun
Maleic anhydride (MAnh) and its derivatives are underutilized monomer classes, each with unique reactivities and properties, which afford the synthesis of highly functional (co)polymers. This review explores the current understanding, opportunities, and limitations associated with maleic anhydride and its derivatives in conventional radical and ...

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

Molecules, 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.

Organotellurium(VI) Azides and Halides^†

, 2016
The reaction of azide with organotellurium(VI) halides Ph5TeBr and cis-(biphen)2TeF2 (biphen = 2,2‘-biphenyldiyl) resulted in the formation and isolation of Ph5TeN3 (1) and cis-(biphen)2Te(N3)2 (2), which are the first tellurium(VI)-azide species.

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

Chemistry, 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]

PLoS 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,

Chalcogen-Guided Control of Azoarene Photoswitching: Tuning Excited-State Energies Through Electronic Property Modulation. [PDF]

Chemistry
Photophysical properties of ortho‐tellurium‐substituted azoarenes are tunable via aryl substituent electronics and tellurium oxidation state. Electron‐donating groups destabilize the excited state three‐electron σ bond, enhancing photoisomerization.
