A straightforward protocol for the preparation of the colorful and air-stable diphenyl ditelluride is described. In one laboratory session, students isolate their product and characterize it via melting point determination, mass spectrometry, and NMR spectroscopy ( 1 H, 13 C{ 1 H}, and 125 Te{ 1 H}). The alternative application of a Grignard reagent serves as a bridge between common organic laboratory experiences and this exercise. Students have the opportunity to see the advantages and disadvantages of the assortment of characterization techniques and, for MS and NMR, the distinctness of their application specifically to inorganic compounds. Analysis of single crystal X-ray diffraction data and molecular modeling results of Ph 2 Te 2 and its lighter congeners (Ph 2 E 2 , E = O−Se) provide students with a data-supported understanding of the inert pair effect.

“…19 Several reviews relating to secondary TeÁ Á ÁN bonding interactions have appeared. 13,[20][21][22][23][24] Benzo [1,3]tellurazole derivatives, characterized by high thermal and oxidation stabilities, 25 are also capable of selfassembly due to TeÁ Á ÁN SBI's or, where feasible, TeÁ Á Ácarbonyl SBI's. 26 A recent example of the latter includes honeycomb-like organic frameworks consisting of cyclic peptides carrying benzo [1,3]tellurazole moieties.…”

Organotellurium compounds define the compounds containing carbon (organic group) and tellurium bond (C–Te). The first organic compound containing tellurium was prepared by Wohler in 1840 after the discovery of the metal by the Austrian chemist F. J. Muller von Reichenstein in the year 1782. The term tellurium was derived from Latin tellus. Tellurium was observed first time in ores mined in the gold districts of Transylvania. Naturally occurring tellurium compounds are present in various forms based on their oxidation states such as TeO2 (+4) and TeO3 (+6). These oxidation states of tellurium compounds are more stable as compared to the other oxidation states. Tellurium is a rare element and is considered a non-essential, toxic element. Tellurium possesses only one crystalline form which consists of a network of spiral chains similar to that of hexagonal selenium. Tellurium is used for the treatment and prevention of microbial infections prior to the development of antibiotics. Hence, the utilization of organotellurium compounds plays a significant role as reagents and intermediates in various organic syntheses.
