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.

用于水中甲酸脱氢的基于吡啶啉酰胺的铱催化剂：酰胺N取代基对活性和稳定性的影响

为了开发用于甲酸在水中脱氢的高效催化剂，我们研究了几种具有各种酰胺配体的Cp * Ir催化剂。具有N-苯基吡啶甲酸酰胺配体的催化剂在60°C下的TOF为118 000 h ^-1。保持恒定速率（TOF> 35000 h ^-1）6小时，在50°C下达到TON 1000000。
