Sulfur, Selenium, and Tellurium Tellurolates

Oxygen tellurolates, R — Te — OH (tellurenic acid) and its derivatives, are discussed in the section on Tellurenic Acid. 

Quite a large number of organic tellurium compounds with a C—Te —S or a C —Te —Se unit have been prepared. Most of the compounds are rather stable towards atmospheric agents. The low molecular mass compounds have a tendency to convert to diorgano ditellurium and diselenium derivatives. 

The divalent tellurium compounds with a C — Te — Y (Y = S, Se) unit in the molecule are stabilized by coordination of tellurium to an electronegative atom appropriately placed in the molecule. Formyl, pyridyl, or azo groups in an ort/ o-position to the tellurium atom in phenyl tellurium compounds provide these coordination sites. X-ray structural investigations of such compounds revealed short Te —O and Te—N contacts  

Irgolic Organic Tellurium Compounds with one Te,C Bond 

Tellurium, evaporated from a resistively heated crucible, reacted with the species formed by applying radio frequency energy to bis[trifluoromethyl] disulfide. One of the products isolated was trifluoromethyl trifluoromethylthio tellurium.
