| Abstract: | Selective hydrogenation of bicarbonate to formate catalyzed by a ruthenium(III) complex, RuIII(edta)] (edta4? = ethylenediaminetetraacetate), at moderate H2 pressure (2–8 atm) and temperature (30–40 °C) is reported. Formation of formate, the only reduction product, was identified by 13C NMR analysis of the resultant reaction mixture. Based on the spectral data, a working mechanism (admittedly speculative) involving the formation of ruthenium(III)-bicarbonate complex, RuIII(edta)(HCO3)]2?, is proposed for the catalytic reaction. |
