Abstract

Abstract : A water-soluble iridium(iii )–hydroxo complex catalyses the production of H2 from paraformaldehyde in water under basic conditions at 298 K. Abstract : Paraformaldehyde was decomposed using an organoiridium complex (1, [Ir III (Cp*)(4-(1 H -pyrazol-1-yl-κ N 2 )benzoic acid-κ C 3 )(H2 O)]2 SO4 ) as a catalyst in water to produce H2 and CO2 in a 2 : 1 molar ratio at room temperature. The catalytic cycle is composed of the reduction of1 by paraformaldehyde under basic conditions to produce formic acid and the hydride complex, which reacts with protons to produce H2 . Formic acid further decomposed to H2 and CO2 with1 .
