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.

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,

1-Butyl-1-chloro-3-methyl-3H-2,1λ4-benzoxatellurole: crystal structure and Hirshfeld analysis [PDF]

open access: yes, 2017
Two independent molecules comprise the asymmetric unit in the title benzoxatellurole compound, C12H17ClOTe. The molecules, with the same chirality at the methine C atom, are connected into a loosely associated dimer by Te...O interactions, leading to a {.
