Catalytic hydrogen production from paraformaldehyde and water using an organoiridium complexElectronic supplementary information (ESI) available: Experimental and kinetic details. See DOI: 10.1039/c4cc06581f
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 )(H 2 O)] 2 SO 4 ) as a catalyst in water to produce H 2 and CO 2 in a 2 : 1 molar ratio at room temperature. The catalytic cycle is composed of the reduction of 1 by par...

| Summary: | Paraformaldehyde was decomposed using an organoiridium complex (

H
-pyrazol-1-yl-κ
N

)benzoic acid-κ
C

)(H

O)]
2
SO
4
) as a catalyst in water to produce H
2
and CO
2
in a 2 : 1 molar ratio at room temperature. The catalytic cycle is composed of the reduction of
1
by paraformaldehyde under basic conditions to produce formic acid and the hydride complex, which reacts with protons to produce H
2
. Formic acid further decomposed to H
2
and CO
2
with

.
A water-soluble iridium(

)-hydroxo complex catalyses the production of H
2
from paraformaldehyde in water under basic conditions at 298 K. |
