A series of di-μ-carboxylatoruthenium complexes of general formula [Ru2(μ-OOCR)2(CO)4L2] were tested as precursors for the hydroformylation reaction of alkenes. It was shown that this reaction requires the CO/H2 couple in the presence of small amounts of water in addition to the solvent. The more active system is represented by [Ru2(μ-OAc)2(CO)4(PPh3)2] and a slight excess of triphenylphosphine (P/Ru=5) at 3 MPa. Although a modest reaction rate was noted (2.5 h-1), aldehydes were selectively obtained, the linear aldehydes being recovered with 80% selectivity in the best conditions. In some cases, especially when the P/Ru ratio=1 or with the less basic ligands, some isomerization of the alkene was observed but hydrogenation of the substrate or of the aldehydes was never detected.
