Oxidation Reactions Promoted or Catalyzed by Organotellurium Compounds [PDF]

ACS Omega
Oxidation of organic substrates is a pivotal transformation, with profound chemical and biological implications. This review covers the synthetic application of organotellurium compounds as promoters or activators of oxidizing agents in such reactions. This research field has evolved from utilizing stoichiometric amounts of organotellurium as oxidizing

Transition-Metal-Free Synthesis of Unsymmetrical Diaryl Tellurides via S_H2 Reaction of Aryl Radicals on Tellurium [PDF]

Molecules, 2022
Although diaryl tellurides are parent organotellurium compounds, their synthesis methods, especially for unsymmetrical ones, are limited. This may be due to the instability of diaryl tellurides and their synthesis intermediates under reaction conditions.

Cytotoxic, Genotoxic, and Mutagenic Effects of Organotellurane RF07 in Female Swiss Mice (Mus musculus). [PDF]

Chem Biodivers
ABSTRACT The organotellurane RF07 (RF07) is an organic compound containing tellurium, a rare semi‐metal, and its leishmanicidal and antimalarial activity has already been reported in previous studies. This study evaluated the toxic effects of RF07 at 0.42, 21.37, and 42.75 mg/kg using comet assay, micronucleus test, and hematological/biochemical tests ...
