Diphenylditelluride is the chemical compound with the formula (C₆H₅Te)₂, abbreviated Ph₂Te₂ This orange-coloured solid is the oxidized derivative of the unstable benzenetellurol, PhTeH. Ph₂Te₂ is used as a source of the PhTe unit in organic synthesis^[1]^{[citation needed]} and as a catalyst for redox reactions.^[2]

Preparation[]

Ph₂Te₂ is prepared by the oxidation of tellurophenolate, which is generated via the Grignard reagent:^[3]

PhMgBr + Te → PhTeMgBr

2PhTeMgBr + 0.5 O₂ + H₂O → Ph₂Te₂ + 2 MgBr(OH)

The molecule has C₂ symmetry.
