==Preparation==
Ph2Te2 is prepared by the oxidation of tellurophenolate, which is generated via the Grignard reagent:〔Crich, D.; Yao, Q. "Diphenyl Ditelluride" in Encyclopedia of Reagents for Organic Synthesis (Ed: L. Paquette) 2004, J. Wiley & Sons, New York. .〕
:PhMgBr + Te → PhTeMgBr
:2PhTeMgBr + 0.5 O2 + H2O → Ph2Te2 + 2 MgBr(OH)
The molecule has ''C2'' symmetry.
