Triphenyl phenyl tellurium trichloride

Triphenyl Telluronium Phenylbromotrichlorotellurate(IV)8 25 ml of chloroform, 1.31 g (3 mmol) of triphenyl telluronium bromide, and 0.93 g (3 mmol) phenyl tellurium trichloride are placed in a 100 ml flask fitted with a reflux condenser. The mixture is heated under reflux for 4 h, the solvent is evaporated, and the residue is recrystallized from dichloromethane/ethyl acetate yield 1.91 g (85%) m.p. 194°. 

Hexaphenyl dilead3, tetramethyl lead3, and triphenyl lead chloride4 donate phenyl groups to aryl tellurium trichlorides to produce aryl phenyl tellurium dichlorides in yields from 73 to 92%. The lead compounds are more reactive than the tin and silicon derivatives and even react at 20°.
