This invention comprises a process for hydrogenation of aldehydes to alcohols using novel homogeneous catalysts. The catalysts are generated in situ under hydrogen and carbon monoxide gases in a suitable solvent, by mixing a rhodium catalyst precursor, such as Rh(CO)

available rutheniumcompound, bis(cyclopentadienylruthenium dicarbonyl) dimer ([CpRu(CO)2]2), was explored. Styrene derivatives or Michael acceptors react readily with either primary or secondary phosphines in the presence of 0.1 mol % of [CpRu(CO)2]2 under photolysis with an inexpensive and commercially available UV/A 9 W lamp. In comparison to related photoactivated hydrophosphination reactions with [CpFe(CO)2]2
