Abstract

Proton transport via a dynamic chemistry method is an essential pathway in both biology and chemistry. In chemical catalysis, proton-shuttling catalysts were developed by mimicking the proton-transport processes in biological systems. However, YH (Y = O, N, S, etc.) units are typically essential for enabling proton transport in these catalysts. Herein, we present a novel strategy for constructing in situ reversible proton-shuttling covalent organic framework catalysts, avoiding the need for Y–H functional groups. Specifically, we demonstrate that the 2D bis(imino)pyridine Cu-bipy-COF material could transform to a water proton-shuttling catalyst by using the reversible interconversion between imine and hemiamine. This catalyst could effectively catalyze the hydration of benzonitrile in neat water without the use of a toxic organic solvent.

促进腈水化的原位可逆形成质子穿梭共价有机骨架催化剂

通过动态化学方法进行质子输运是生物学和化学的重要途径。在化学催化方面，质子穿梭催化剂是通过模拟生物系统中的质子传递过程而开发出来的。然而，YH （Y = O， N， S等）单元对于在这些催化剂中实现质子输运通常是必不可少的。在此，我们提出了一种新的策略来构建原位可逆质子穿梭共价有机框架催化剂，避免了对Y-H官能团的需要。具体来说，我们证明了二维双（亚胺）吡啶Cu-bipy-COF材料可以通过亚胺和半胺之间的可逆相互转化转化为水质子穿梭催化剂。该催化剂可以在不使用有毒有机溶剂的情况下，有效地催化苯腈在纯水中的水化反应。
