Abstract
Reaction of [(η5-Cp)Ru(PPh3)2Cl] (1) with excess para-amino-N-(pyrid-2-ylmethylene)-phenylamine ligand (app) in methanol in the presence of NH4BF4 leads to the formation of [η5-CpRu(PPh3)(aap)]BF4 (6BF4). Similarly, [(η5-ind)Ru(PPh3)2(CH3CN)]BF4 (4BF4) and [(η5-Cp*)Ru(PPh3)2(CH3CN)]BF4 (5BF4) react with app to yield the cationic complexes [(η5-ind)Ru(PPh3)(app)]BF4 (7BF4) and [(η5-Cp*)Ru(PPh3)(app)]BF4 (8BF4), respectively. The complexes were characterized by analysis and spectroscopic data. The structure of a representative complex (6BF4) was established by single-crystal X-ray methods.
