[Abstract] The hydrogenation of unsaturated compounds is a key technology in the chemical industry. The efficient catalytic reduction of water for generation of hydrogen is one of the most challenging transformations in chemistry.
We continuously investigated the potential application of iron (commercial iron powder) to activate water as a terminal hydrogen source without any stoichiometric acid or base. Here in we are pleased to disclose the external-pressure-free and mild reaction protocol for reduction of alkenes using a cheap, non-hazardous, abundant, and eco-friendly ¡°water/iron¡± pair as a hydrogen donor in the presence of a Pd/C catalyst (2.5 mol % w.r.t. substrate).
Pd/C-catalyzed hydrogenation of olefins by using water as a hydrogen source in the presence of iron powder gave the corresponding reduction products in ¡Ü 96% yield (GC Yield). The formation of Fe3O4 as a byproduct was confirmed by XRD analysis.
