摘要：
Interconversion between hydrogen and formic acid in water at ambient temperature and pressure has been made possible by using a [C,N] cyclometalated organoiridium complex, [Ir-III(Cp*)(4-(1H-pyrazol-1-yl-kappa N-2) benzoic acid-kappa C-3)(H2O)](2)SO4 [1](2)center dot SO4, as an efficient catalyst for both directions depending on pH. Hydrogenation of carbon dioxide by hydrogen occurs in the presence of a catalytic amount of 1 under an atmospheric pressure of H-2 and CO2 in weakly basic water (pH 7.5) at room temperature, whereas formic acid efficiently decomposes to afford H-2 and CO2 in the presence of 1 in acidic water (pH 2.8).
