Allgemeine Beschreibung

Atomic number of base material: 52 Tellurium

Anwendung

  • Highly efficient regioselective synthesis of organotellurium compounds: Explores the reactions of Tellurium Tetrachloride with 1-alkenes, highlighting its utility in organic synthesis (VA Potapov et al., 2017).
  • Cyclization Reactions: TeCl4 acts as a bis-electrophile in double-electrophilic cyclization reactions, demonstrating its versatility in organic transformations (N Korol, M Slivka, 2018).
  • Regio-and stereoselective addition of tellurium tetrachloride: Investigates the addition of TeCl4 to methyl propargyl ether, emphasizing the stereochemistry of the addition process (MV Musalova et al., 2017).

The reaction of tellurium tetrachloride with acetylene proceeds in a stereospecific anti-addition manner to afford the novel products E-2-chlorovinyltellurium trichloride and E,E-bis(2-chlorovinyl)tellurium dichloride. Reaction conditions for the selective preparation of each of these products were found. The latter was obtained

Diphenyl ditelluride (DPDT) and tellurium tetrachloride (TeCl(4)) were evaluated for toxicity in transformed (HT-29, Caco-2) and non-transformed colon cells (CCD-18Co). Significant decreases in viability were observed with DPDT exposure in HT-29 (62.5-1000 μM), Caco-2 (31.25-1000 μM) and CCD-18Co cells (500-1000

Tellurium tetrachloride (TeCl(4)) and diphenyl ditelluride (DPDT) cytotoxicity, was investigated in rat astrocytes. Concentrations of 0.24-250μM (24h) were tested for viability using MTT(3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide) and trypan blue exclusion. MTT showed significant decreases at all concentrations tested for both compounds.
