Three half‐sandwich ruthenium(II) complexes with hydroxyl group functionalized Schiff‐base ligands [Ru( p ‐cymene)LCl] ( 2a‐2c ) have been synthesized and characterized. All ruthenium complexes were fully characterized by 1 H and 13 C NMR spectra, mass spectrometry and infrared spectrometry. The molecular structure of ruthenium complex 2c was confirmed by single‐crystal X‐ray diffraction methods. Furthermore, these half‐sandwich ruthenium complexes were found to exhibit high catalytic activity for nitro compounds reduction using NaBH 4 reducing agent in the presence of cetyltrimethylammonium bromide (CTAB) in water at room temperature.
