摘要: Abstract The complex [{(η6-p-cymene)Ru(μ-Cl)Cl}2] (1) reacts with benzylamine to give a neutral N-coordinated of the type [(η6-p-cymene)Ru(NH2CH2C6H5)Cl2] (2). [(η6-p-cymene)Ru(PPh3)Cl2] (3) amine ligands yield chiral complexes [(η6-p-cymene)Ru(PPh3)(NH2-R)Cl]+ [R = CH2C6H5 (4a), p-ClC6H4 (4b), p-NO2C6H4 (4c)]. Complexes 1 and 3 react N,N-donor chelating 1,2-phenylenediamine (PDA) giving cationic 5 6, respectively. [(η6-C6Me6)Ru(μ-Cl)Cl]2 (7) diphenyl-2-pyridylphosphine P-coordinated ruthenium(II) [(η6-C6Me6)Ru(PPh2Py)Cl2] (8) as well P,N-chelating [(η6-C6Me6)Ru(PPh2Py)Cl]+ (9). 9 undergoes substitution reactions acetonitrile 1,1-diphenyl-2-propyn-1-ol ligands. These were characterized by FT-IR FT-NMR spectroscopy analytical data. molecular structures representative (2), [(η6-C6Me6)Ru(PPh2Py)Cl]BF4 (9) established single-crystal X-ray diffraction studies.
