Abstract

A series of new arsine-dihydrido ruthenium(II) complexes, [RuH2(CO) (AsPh3)3] (1) and [RuH2(CO)(AsPh3)(L-L)], [L-L = diars (2), arphos (3), diphos (4)], has been synthesized and characterized by IR, 1H NMR and elemental analysis. The catalytic activities of these complexes for the hydrogenation of propionaldehyde to yield propan-1-ol have been examined at 130°C and 30 atm hydrogen pressure, and compared with the catalytic activity of the well-known complex, [RuH2(CO)(PPh3)3] (5). [RuH2(CO) (AsPh3)3] showed lower catalytic activity than that of [RuH2(CO) (PPh3)3]. Complexes having a chelate ring have shown higher catalytic activities than that of [RuH2(CO)(AsPh3)3]. Overall, the catalytic activities were found to decrease in the order 4 > 3 > 2 > 5 > 1.
