New (η6?p?cymene) ruthenium(II) complexes containing Schiff base ligands of the general composition [RuCl(η6?p?cymene)(L1?3)] have been synthesized. The complexes were characterized by analytical and spectral (FT?IR, UV–Vis, 1H NMR and 13C NMR) methods. The molecular structure of the representative complex [RuCl(η6?p?cymene)(L3)] 6 was determined by single crystal X?ray diffraction studies, revealing a pseudo-octahedral piano stool geometry around ruthenium(II) ion. Further, one of the complexes 6 was screened for their efficiency as a catalyst in the transfer hydrogenation of various ketones to alcohols in the presence of KOH and 2?propanol showed an excellent conversion up to 99%. Under the optimized conditions, the influence of base, reaction temperature and substrate scope was also reported.
