Abstract

An improved procedure for the preparation of the known H 2O-soluble hydrogenation and hydroformylation catalyst, [RuH(Cl)(CO)(mtppms)3] (mtppms = meta-monosulfonated triphenylphosphine) was developed. In contrast to the methods reported earlier, this synthesis yields the complex free of mtppms impurities. 1H- and 31P{H}-NMR measurements revealed that in aqueous solution, [RuH(Cl)(CO)(mtppms)3] reversibly dissociated to give [RuH(CO)(H 2O)(mtppms)3]+ (Scheme). The equilibrium constant of this dissociation was determined as 9.8·10-2 M at 293 K. Such a dissociation was not observed in MeOH but took place to varying degrees in MeOH/H2O mixtures of varying composition. [RuH(CO)(H 2O)mtppms)3][BF4] was also obtained on an independent synthetic route: by ligand exchange in [RuH(CO)(NCMe) 2(PPh3)2][BF4] (Scheme). The results may help the understanding of the mechanisms of reactions catalyzed by [RuH(Cl)-(CO)(mtppms)3] in aqueous solutions or in aqueous-organic biphasic systems.
