With Cleavage of the Tellurium-Carbon Bond

The precipitation of black tellurium frequently encountered in reactions carried out with tellurols or tcllurolates indicates that the carbon-tellurium bond is prone to cleavage under rather mild conditions. Alkanetellurols and -tcllurolates appear to be less stable than the aromatic compounds. Exposure of tcllurolates to air and water causes at least partial decomposition of arenetellurolates and ethynetellurolates to elemental tellurium. 

Irgolic Organic Tellurium Compounds with one Te,C Bond 

The aryl-tellurium bond in bromomagnesium benzenetellurolate is cleaved during its reaction with trimethylsilyl chloride, because bis[trimethylsilyl tellurium was observed as a reaction product  

When sodium benzenetellurolate was treated with sodium in liquid ammonia, the carbon-tellurium bond was cleaved. Benzene was isolated after work-up.  

Disodium methaneditellurolate disproportionated in ethanol to disodium telluride and polymeric telluroformaldehyde.
