Pentafluorophenyl phenyl telluride (1) and 3,5-dichloro-2,4,6-trifluorophenyl phenyl telluride (2) react with pentafluorophenyllithium or 3,5-dichloro-2,4,6trifluorophenyllithium in THF at low temperatures to form the corresponding tellurium ate complexes (A) and (B) as sole intermediates in the lig
