Convenient Synthesis of bis-Bipyridines and bis-Terpyridines Bridged by Phenyl and Biphenyl Tethers

Abstract

A simple three step preparation of phenyl bridged bis-2,2′-bipyridine and bis-2,2′:6′,2”-terpyridine from readily available reagents is described. The compounds have the potential to serve as rigid bridging ligands for the preparation of redox and photoactive supramolecular complexes of transition metals.
