Bis(4-pyridyl)ditelluride as starting material for the synthesis of zwitterionic compounds and metal complexes

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.

Experimental evidence for hypercoordination in triorganotelluronium halides with 2-(Me2NCH2)C6H4 groups

Triorganotelluronium halides of type [{2-(Me₂NCH₂)C₆H₄}_nPh_3−nTe]⁺X⁻ (n = 1–3, X = Cl, Br, I) were prepared and structurally characterized both in solution and in the solid state, showing a (C,N)-chelating behavior of the 2-(Me₂NCH₂)C₆H₄ groups.
