Organotellurium(II) and ‐(IV) Compounds with Picolinoylbis(thio­ureas): From Simple 1:1 Adducts to Multimetallic Aggregates

European Journal of Inorganic Chemistry, Volume 27, Issue 29, October 11, 2024.
Reactions of 2,6‐dipicolinoylbis(N,N‐diethylthiourea) (H2LEt) with common tellurium(IV) starting materials such as PhTeBr3 or TeBr4 yield various tellurium(IV) and tellurium(II) compounds depending on the conditions applied.

Synthesis, antimicrobial activity, computational and modeling studies of some new organotellurium compounds containing azo moities [PDF]

, 2015
A new series of organonotellurium compounds containing azo groups were prepared by new and convenient methods. Reaction of 1-(4-mercuric chloride-2,3-dichlorophenyl)-2-chloro diazine (4) with 8-hydroxyquinoline (5) gave the new organomercury compound 6 ...

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 ...

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.

Dihalogens Binding and Activation by Imidazoline-2-Chalcogenone Model Derivatives: Insight from a Computational Approach. [PDF]

Chemistry
1,3‐dimethyl‐4‐imidazoline‐2‐chalcogenones react with dihalogens, initially forming a charge‐transfer (CT) adduct, which may evolve to the most stable T‐shaped hypercoordinate (TY) species. However, in silico results show that the CT adduct is more stable than the corresponding TY species for the sulfur and iodine combination.
