    Ruthenium Catalyzed Hydrogenation of Aldehyde with Synthesis Gas
    摘要:
    The hydrogenation of aldehyde utilizing synthesis gas as a dihydrogen source was examined with various ruthenium catalysts, among which Rucyclopentadienone complexes (Shvo-type catalysts) exhibited higher activity than others. DFT calculations proved that the exchange of coordinated carbon monoxide by dihydrogen is relatively preferable in Shvo-type catalysts compared to others, which is a pre-equilibrium for the generation of the hydrogenation-active species.

  • Microwave-Assisted Synthesis of Functionalized Shvo-Type Complexes
    作者:Cristiana Cesari、Letizia Sambri、Stefano Zacchini、Valerio Zanotti、Rita Mazzoni
    DOI:10.1021/om500335m
    日期:2014.6.9
    A simple and expeditious microwave-assisted procedure for the synthesis of a variety of Shvo-type ruthenium complexes has been developed by reacting Ru-3(CO)(12) with variously functionalized tetraarylcyclopentadienones under microwave irradiation in MeOH. Ligand precursors have also been prepared under microwave heating by a bis-aldol condensation of 1,3-diphenylacetone with variously functionalized aromatic diketones. All the reactions were very fast and clean, leading to good yields and purities.
  • Catalytic disproportionation of aldehydes with ruthenium complexes
    作者:Naim Menashe、Youval Shvo
    DOI:10.1021/om00057a019
    日期:1991.11
    It was discovered that the ruthenium complex [(C4Ph4COHOCC4Ph4)(mu-H)][(CO)4Ru2] (2), as well as other isostructural Ru complexes, in the presence of a catalytic amount of formic acid, catalyzes the homogeneous bimolecular disproportionation reaction of aldehydes to give esters: 2RCHO --> RCOOCH2R. The reaction was found to be general and compatible with a variety of aliphatic and aromatic aldehydes and can be carried out in the presence or absence of solvent under mild conditions. It is characterized by an excellent efficiency with an initial turnover frequency reaching 5000 h-1, a measured overall turnover number of ca. 20 000, and high conversion, yield, and selectivity. Increasing the electron density on the metal and the ligand was found to accelerate the reaction. Kinetic studies indicate that the rate = k[catalyst]1/2[aldehyde]. The rate also depends on the initial formic acid concentration. A stoichiometric reaction of complex 2 with formic acid, monitored by infrared spectroscopy, shed light on the identity of the active catalytic species. No kinetic isotope effect could be detected by using PhCDO and DCOOD as reactants. Consequently, a mechanism and a detailed catalytic cycle for the bimolecular transformation of aldehydes to esters were proposed.
