Özet
Two novel versatile tridendate aminophosphine-phosphinite and phosphinite ligands were prepared and their trinuclear neutral ruthenium(II) dichloro complexes were found to be effective catalysts for the transfer hydrogenation of various ketones in excellent conversions up to 99% in the presence of 2-propanol/NaOH in 0.1M isopropanol solution. Particularly, [Ru-3(PPh2OC2H4)(2)N-PPh2((6)-p-cymene)(3)Cl-6] acts as an excellent catalyst giving the corresponding alcohols in excellent conversion up to 99% (turnover frequency1176h(-1)). A comparison of the catalytic properties of the complexes is also discussed briefly. Furthermore, the structures of these ligands and their corresponding complexes have also been clarified using a combination of multinuclear NMR spectroscopy, infrared spectroscopy and elemental analysis. H-1-C-13 HETCOR or H-1-H-1 COSY correlation experiments were used to confirm the spectral assignments. Copyright (c) 2014 John Wiley & Sons, Ltd.
