From Aryl Triphenylstannyl germyl Tellurium

Phenyl triphenylgermyl or triphenylstannyl tellurium transferred the benzenetellurolate group to palladium in a reaction with bis[benzonitrile]dichloropalladium(II).  

Bis[benzenetellurolato]palladium To a solution of 0.48 g (1.25 mmol) of bis[benzonitrile]palladium dichloride in 50 m/ of chloroform are added 1.27 g (2.5 mmol) of phenyl triphenylgermyl tellurium, the mixture is stirred at 20° for 24 h, and then filtered. The brown solid is washed thoroughly with diethyl ether and dried yield 0.55 g (85%) m.p. 142°. 

Aryl triphenylstannyl tellurium reacted with 1,5-cyclooctadienedichloropalladium in chloroform at 20°. With equimolar amounts of the reagents 1,5-cyclooctadienechloro (arenetellurolato)palladiums were isolated with 2 moles of tellurium compound per mole of palladium complex, 1,5-cyclooctadiene bis[arenetellurolato]palladiums were obtained.
