Bis(2-nitrophenyl) selenide, bis(2-aminophenyl) selenide and bis(2-aminophenyl) telluride: Structural and theoretical analysis

Three organoselenium and organotellurium compounds containing ortho substitutents, namely, bis(2-nitrophenyl) selenide, C12H8N2O4Se, 2, bis(2-aminophenyl) selenide, C12H12N2Se, 3, and bis(2-aminophenyl) telluride, C12H12N2Te, 7, have been investigated by

Non-covalent bridging of bithiophenes through chalcogen bonding grips

In this work, chalcogen functionalized dithiophenes, equipped on both extremities with chalcogen-bonding recognition heterocycles, have been prepared following two synthetic pathways. The insertion of the chalcogenazolo[5,4-β]pyridine allows the control of the organization at the solid state. X-Ray diffraction analysis of the single crystals, showed that the Te-doped derivatives give the most persistant assemblies, with the molecules arranging at solid-state in wire-like polymeric structures through Te?N interactions. As expected, the introduction of the Se and Te atoms, dramatically decreases the emission properties, with the Te-bearing congeners being virtually non emissive.

The synthesis, X-ray crystal structures, ground- and excited-state UV/Vis absorption spectra, and luminescence properties of chalcogen-doped organic emitters equipped on both extremities with benzoxa-, benzothia-, benzoselena- and benzotellurazole (1

Organotellurium chemistry: Remarkably facile preparation of benzo-1,3-tellurazoles

Benzo-1,3-tellurazoles carrying alkyl or aryl substituents in position 2 were prepared in a facile two-step sequence, starting with readily available 2-haloanilines. This approach relies on the preparation of bis(2-aminophenyl) ditellurides by nucleophilic halide displacement from 2-haloanilines with sodium telluride in N-methylpyrrolidone. Subsequent reductive cyclization with carboxylic acid halides or carboxylic anhydrides furnished benzo-1,3- tellurazoles in good yields.

Microwave-assisted one-pot synthesis of symmetrical diselenides, ditellurides and disulfides from organoyl iodides and elemental chalcogen catalyzed by CuO nanoparticles

In this study CuO nanoparticles were applied as a catalyst for CSe, CTe, and CS bond formation. The reaction was performed with organoyl iodides and elemental selenium, tellurium or sulfur under microwave irradiation in the presence of a base and solvent at 80 °C. This novel protocol allowed the synthesis of a variety of diselenides, ditellurides and disulfides in good to excellent yields in a very short reaction time.

An efficient one-pot synthesis of symmetrical diselenides or ditellurides from halides with CuO nanopowder/Se0 or Te0/base

(Equation Presented). A CuO nanopowder-catalyzed coupling reaction of aryl, alkyl, and heteroaryl iodides with elemental selenium and tellurium takes place in the presence of KOH at 90 °C in DMSO. A wide range of substituted symmetrical diselenides and ditellurides were afforded with good to excellent yields.

Synthesis of azido arylselenides and azido aryldiselenides: a new class of selenium-nitrogen compounds

We present here our results of the efficient synthesis of azido arylselenides and azido aryldiselenides under mild conditions. Starting from nitrogen-substituted benzenes, we incorporated selenium atom at aromatic ring and obtained amino arylselenides and diselenides in satisfactory yields. Treatment of these compounds with iso-pentyl nitrite (i-C5H11ONO) and azido trimethylsilane (Me3SiN3) in THF affords a variety of azido arylselenides and diselenides in good to excellent yields.

Thiol peroxidase activity of diaryl ditellurides as determined by a 1H NMR method

A 1H NMR method was developed for the assessment of the glutathione peroxidase-like activity of synthetic compounds. In this assay, thiols (N-acetylcysteine, tert-butyl mercaptan and 1-octyl mercaptan) were oxidized to the corresponding disulfides in CD3OD or CD3OD/D2O in the presence of hydrogen peroxide and the catalyst to be evaluated. The time required to reduce the thiol concentration with 50%, t50, was determined as a measure of the thiol peroxidase activity of the catalyst. Several diaryl ditellurides were efficient catalysts when present in low concentrations (0.3 mol %), whereas compounds with well-documented glutathione peroxidase-like activity in other assays were inactive (Ebselen, diaryl diselenides). The glutathione peroxidase-like activity of diaryl ditellurides was also assessed by using the classical coupled reductase assay. A mechanistic study showed that diaryl ditellurides, in the presence of hydrogen peroxide and a thiol, were rapidly converted to tellurosulfides. These species were stable enough to be isolated in some cases. The tellurosulfides reacted very slowly with added thiol, but in the presence of thiol/hydrogen peroxide the thiol was rapidly converted to its corresponding disulfide. On the basis of these observations, a mechanism involving a tellurinic acid thiol ester was proposed for the thiol peroxidase reaction of ditellurides. In contrast to tellurosulfides, selenosulfides, obtained either from diphenyl diselenide/hydrogen peroxide/1-octyl mercaptan or from Ebselen and 1-octyl mercaptan, were found to react very slowly with thiols in the presence of hydrogen peroxide.

Nitrogen-Tellurium Heterocycles. 1. Preparation of Benzotellurazoles and Their Derivatives

Cyclization of previously isolated and purified N-acyl derivatives of α-methyltelluroaniline under the influence of POCl3 leads to 2-R-benzotellurazoles in yields of 35-65percent. 1,1-Dichloro-2-R-benzotellurazoles are intermediates in this reaction.
