Abstract

To develop highly efficient catalysts for dehydrogenation of formic acid in water, we investigated several Cp*Ir catalysts with various amide ligands. The catalyst with an N-phenylpicolinamide ligand exhibited a TOF of 118 000 h−1 at 60 °C. A constant rate (TOF>35 000 h−1) was maintained for six hours, and a TON of 1 000 000 was achieved at 50 °C.
