Özet
Four new ruthenium(II) complexes [RuCl(1-4)(p-cymene)] (1-4 = N-(3-(2-hydroxybenzylideneamino)phenyl) benzenesulfonamides) were synthesized from [RuCl2(p-cymene)](2) with Schiff base ligands containing aromatic sulfonamide fragment, and characterized by spectroscopic techniques including H-1 and C-13 NMR, FT-IR, single crystal X-ray diffraction and by elemental analysis. Additionally, all the synthesized Ru(II) complexes were tested as catalysts for the reactions in the transfer hydrogenation (TH) of acetophenone derivatives. The results showed that these facile synthesized Ru(II) complexes are efficient catalysts in this reaction (turnover frequency: 1260 h(-1) for 6). (C) 2014 Elsevier B. V. All rights reserved.
