Abstract

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, [IrIII(Cp*)(4-(1H-pyrazol-1-yl- κN2)benzoic acid-κC3)(H2O)] 2SO4 [1]2·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 H2 and CO2 in weakly basic water (pH 7.5) at room temperature, whereas formic acid efficiently decomposes to afford H2 and CO2 in the presence of 1 in acidic water (pH 2.8).
