Synthesis, Characterization and Theoretical Studies of New Organotellurium Compounds Based on (4-(((1S,E)-1,7,7-trimethylbicyclo[2.2.1]heptan-2-ylidene)amino)phenyl)mercury(II) Chloride

The current study aimed to prepare new organomercury and organotellurium compounds based on the condensation reaction of 1,7,7-trimethylbicyclo[2.2.1]heptan-2-one (camphor) and p-aminophenyl mercuric(II) chloride. All the prepared compounds were characterized using different methods such as infrared spectrum, nuclear magnetic resonance, and CHN analysis. The analysis results concurred with the suggested chemical structures of the prepared compounds. Density functional theory has been applied with the basis set 3-21G to investigate the molecular structure of the prepared organotellurium compounds. Geometrical structure, HOMO surfaces, LUMO surfaces, and energy gap have been produced throughout the geometry optimization. The molecular geometry and contours for organotellurium compounds have been investigated throughout the geometrical optimization. Also, the donor and acceptor have been studied by comparing the HOMO energies of the prepared organotellurium compounds. Finally, the electronegativity, electrophilicity, ionization potential, electron affinity, and lower case of organotellurium compounds have been calculated and discussed.

Organotellurium compounds: an overview of synthetic methodologies

In wake of emerging applications of organotellurium compounds in biological and material science avenues, the current review describes their key synthetic methodologies while focusing the synthesis of organotellurium compounds through five ligand-to-metal linkages including carbon; carbon-oxygen; carbon-nitrogen; carbon-metal; carbon-sulfur to tellurium. In all of these linkages whether tellurium links with ligands through a complicated or simple pathways, it is often governed through electrophilic substitution reactions. The present study encompasses these major synthetic routes so as to acquire comprehensive understanding of synthetic organotellurium compounds.

Oxidation of Thiol Using Ionic Liquid-Supported Organotelluride as a Recyclable Catalyst

Organotellurium compounds are known to be useful oxidation reagents. For developing a recoverable and reusable reagent, this paper describes the use of an ionic liquid (IL) support for the organotellurium reagent and its application as a recyclable catalyst for thiol oxidation. We have successfully prepared a novel diphenyl telluride derivative 5 bearing an imidazolium hexafluorophosphate group in its structure. It is found that the IL-supported diphenyl telluride 5 efficiently catalyzed the aerobic oxidation of various thiols in [bmim]PF6 solution under photosensitized conditions to provide the corresponding disulfides in excellent yields. The product can be isolated by simple ether extraction. The IL-supported catalyst 5 remaining in the ionic liquid phase can be reused for five successive runs while retaining high catalytic activity (97% yield even in the fifth run).
