A series of mono- and bis(2-pyridyl)-arylmethanone ligands were prepared by utilizing the reaction between either bromobenzonitrile or dicyanobenzene and 2-lithiopyridine in either a 1:1 or a 2:1 mol ratio, respectively. They react with [Ru(bpy)2(EtOH)2][PF6]2 to yield the new complexes [N,O-PhC(O)(2-py)Ru(bpy)2][PF6]2 (6), [p-N,O-BrC6H4C-(O)(2-py)Ru(bpy)2][PF6]2 (7), [m-N,O-BrC6H4C(O)(2-py)Ru(bpy)2][PF6]2

The m- and p-phenylene-bridged bis-azolopyridinium salts have been synthesized and converted into the corresponding bis-dienamines by reaction with pyrrolidine. These dienamines react readily with dimethyl 1,2,4,5-tetrazine-dicarboxylate to yield the bis-azolylvinyl-pyridazines.
