A highly efficient Ir-catalyst for the solventless dehydrogenation of formic acid: the key role of an N-heterocyclic olefin

A sturdy iridium complex that features a PCP ligand based on an N-heterocyclic olefin shows remarkable activity for the solventless dehydrogenation of formic acid. Reactivity studies highlight the importance of NHO in the activity of the catalyst. A plausible intermediate has been isolated and the m...

Sumario:A sturdy iridium complex that features a PCP ligand based on an N-heterocyclic olefin shows remarkable activity for the solventless dehydrogenation of formic acid. Reactivity studies highlight the importance of NHO in the activity of the catalyst. A plausible intermediate has been isolated and the mechanism was substantiated by DFT calculations.
