Abstract

Copper(I) hydride complexes are typically known to react with CO₂ to form their corresponding copper formate counterparts. However, recently it has been observed that some multinuclear copper hydrides can feature the opposite reactivity and catalyze the dehydrogenation of formic acid. Here we report the use of a multinuclear PNNP copper hydride complex as an active (pre)catalyst for this reaction. Mechanistic investigations provide insights into the catalyst resting state and the rate-determining step and identify an off-cycle species that is responsible for the unexpected substrate inhibition in this reaction.

氢化铜（I）催化甲酸脱氢的机理研究

众所周知，氢化物铜（I）络合物通常会与二氧化碳反应生成相应的甲酸铜。然而，最近观察到一些多核氢化物铜具有相反的反应性，可以催化甲酸的脱氢反应。在此，我们报告了使用多核 PNNP 氢化物铜配合物作为该反应的活性（前）催化剂的情况。机理研究深入揭示了催化剂静止状态和速率决定步骤，并确定了一种非循环物种，该物种是导致该反应中出现意外底物抑制的原因。
