摘要: Pentafluorophenyl phenyl telluride and 3,5-dichloro-2,4,6-trifluorophenyl reacted with pentafluorophenyllithium or 3,5-dichloro-2,4,6-trifluorophenyllithium at low temperature to form the corresponding tellurium ate complexes as sole intermediates of ligand exchange on hypervalent centers. In these electron-withdrawing aryl ligands were arranged apical positions exchanges took place between apical-directing groups.
