Abstract

The synthesis of trisubstituted 4′, 5, 5′′ terpyridines is described. The strategy begins with synthesis of 2-acetyl-5-bromopyridine (3) from 2, 5-dibromopyridine, substitution of the bromine in 3 using a variety of metal-catalyzed reactions and then formation of the terpyridine using the Krohnke reaction. The complexes have been prepared by reaction of [Pt (PhCN) 2Cl2] with the appropriate silver salt followed by addition of the terpyridyl ...
