Abstract

The complexes MHCl(CO)(AsPh3)3 (1: M=Ru and 2: M=Os) readily react with Ph2PCH2CH2AsPh2 (Arphos) to yield MHCl(CO) (AsPh3) (Arphos) (3: M=Ru and 4: M=Os) and with acetic acid to produce MCl(CO) (OCOMe) (AsPh3)2 (5: M=Ru and 6: M=Os); the new compounds were characterized by elemental analysis, i.r. and1H n.m.r. spectroscopy. Complexes (1-6) are efficient catalyst precursors for the homogeneous hydrogenation of the C=O bond of propionaldehyde under moderate reaction conditions; some relations between structures and catalytic activities are described, as well as comparisons with analogous systems containing phosphine ligands.
