Abstrakt: With water tricarbonyl-tetrahapto-tetraphenylcyclopentadienoneruthenium(O) (1) undergoes a water-gas type reaction whereby a coordinated CO is oxidized to CO2, and gives the dimeric complex, which was isolated in high yield. A catalytic reduction of ketones with CO and water under mild conditions has been developed, and a catalytic cycle proposed. A turnover frequency of 1.2 min−1, which is increased by a factor of ca. 6 by the presence of sodium carbonate, has been observed in the reactions with cyclohexanone.
