Three half-sandwich ruthenium(II) p-cymene complexes containing naphthalenebased Schiff base ligands [Ru(p-cymene)LCl](2 a~2 c) have been synthesized and characterized. Both Schiff-base ligands and ruthenium complexes were fully characterized by ~1H and ~(13)C NMR spectra, mass spectrometry and infrared spectrometry. The molecular structure of ruthenium complex 2 b was confirmed by single-crystal X-ray diffraction methods. For the complex: C_(24_H_(23)ClN_2ORu, M_r = 524.02, monoclinic, space group P21/c, a = 12.3888(4), b = 17.3296(6), c = 20.7744(7) ?, β = 92.8000(10)°, V = 4454.8(3) ?~3, Z = 8, Dc = 1.563 g/cm~3, μ = 0.936 mm~(-1), F(000) = 2128, S = 1.154, the final R = 0.0309 and w R = 0.0703. Moreover, these ruthenium complexes are active catalysts for the hydrogenation of nitroarenes to aromatic anilines in the presence of sodium tetrahydroborate(NaBH_4) reducing agent.
Both Schiff-base ligands and ruthenium-based complexes are fully characterized (2 a ~ 2 c) have been synthesized characterized by ~ 1H and ~ (13) C NMR spectra, mass spectrometry and infrared spectrometry. The molecular structure of ruthenium complex 2 b was confirmed by single-crystal X-ray diffraction methods.
