With water tricarbonyl-tetrahapto-tetraphenylcyclopentadienoneruthenium(0) (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.
