Silver(I) Assisted Metal Exchange Reaction. A Generalized Synthesis of Tris-Chelated Copper(II) Complexes of Neutral N,N-Donors

A novel and direct synthetic route for the syntheses of hexacoordinated cupric complexes involving bidentate N,N-donor ligands has been elaborated. This synthetic strategy has been successfully applied for the preparation of mixed-ligand tris(chelates).
