Synthesis of multifunctional ligands: a 2,9-diaryl-1,10-phenanthroline/2,2′:6′,2″-terpyridine conjugate

The synthesis of a ligand including a 1,10-phenanthroline and a 2,2′:6′,2″-terpyridine separated by a 1,3-phenylene spacer is presented. The different aromatic carboncarbon bonds have been generated by reactions with organolithium compounds, and by Stille and Suzuki couplings.
