Molecular Iridium Complexes in Metal-Organic Frameworks Catalyze CO Hydrogenation via Concerted Proton and Hydride Transfer.
Molecular iridium catalysts immobilized in metal-organic frameworks (MOFs) were positioned in the condensing chamber of a Soxhlet extractor for efficient CO hydrogenation. Droplets of hot water seeped through the MOF catalyst to create dynamic gas/liquid interfaces which maximize the contact of CO,...

Droplets of hot water seeped through the MOF catalyst to create dynamic gas/liquid interfaces which maximize the contact of CO, H, HO, and the catalyst to achieve a high turnover frequency of 410 h under atmospheric pressure and at 85 °C. H/D kinetic isotope effect measurements and density functional theory calculations revealed concerted proton-hydride transfer in the rate-determining step of CO hydrogenation, which was difficult to unravel in homogeneous reactions due to base-catalyzed H/D exchange. pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: Y dt: @attributes: year: 2017 holdings: @attributes: islocal: N |
