Cs. Yi et al., Transfer hydrogenation of carbonyl compounds catalyzed by a ruthenium-acetamido complex: Evidence for a stepwise hydrogen transfer mechanism, ORGANOMETAL, 20(17), 2001, pp. 3641-3643
The ruthenium-acetamido complex, prepared from the reaction of [(PCy3)(2)(C
O)(CH3CN)(2)RuH](+)-BF4- with KOH in 2-propanol, was found to be an effecti
ve catalyst for the transfer hydrogenation of carbonyl compounds and imines
. Observation of both the inverse deuterium isotope effect and the competit
ive inhibition by added phosphine provided strong evidence for a stepwise m
echanism of proton and hydride transfer via a coordinatively unsaturated ru
thenium-amido species.
