The selective dehydrogenation of formic acid by iridium(III) Cp*(dipyridylamine) catalysts is reported. The electron‐enriched catalyst [Ir^IIICp*{(4‐dimethylaminopyridin‐2‐yl‐κΝ)(pyridin‐2′‐yl‐κΝ)amine}(OSO₃)] gave the best performances enabling the base free dehydrogenation of aqueous and neat formic acid. In both cases the reaction was selective with no carbon monoxide detectable. The Ir^III complex demonstrated latent behavior, which may be of practical utility. Experimental results suggest an outer‐sphere interaction with the ligand.

铱（III）Cp *（二吡啶胺）催化剂对甲酸和水性甲酸进行无碱脱氢

报道了铱（III）Cp *（二吡啶胺）催化剂对甲酸的选择性脱氢。电子富集的催化剂的[Ir ^III的Cp * {（4-二甲基氨基吡啶-2-基- κ Ν）（吡啶-2'-基-κ Ν）胺}（OSO ₃）〕得到最好的性能使该游离碱脱氢含水和纯甲酸。在这两种情况下，反应都是选择性的，没有可检测到的一氧化碳。Ir ^III配合物表现出潜在的行为，可能具有实际用途。实验结果表明与配体的外层相互作用。
