Metal hydrides are key intermediates in catalytic proton reduction and dihydrogen oxidation There is currently much interest in appending proton relays near the metal center to accelerate catalysis by proton-coupled electron transfer (PCET). However, the elementary PCET steps and the role of the proton relays are still poorly understood, and direct kinetic studies of these processes are scarce. Here, authors report a series of tungsten hydride complexes as proxy catalysts, with covalently attached pyridyl groups as proton acceptors. The rate of their PCET reaction with external oxidants is increased by several orders of magnitude compared to that of the analogous systems with external pyridine on account of facilitated proton transfer. Moreover, the mechanism of the PCET reaction is altered by the appended bases. A unique feature is that the reaction can be tuned to follow three distinct PCET mechanisms-electron-first, proton-first or a concerted reaction-with very different sensitivities to oxidant and base strength. Such knowledge is crucial for rational improvements of solar fuel catalysts. In addition to this study using 2-(Chloromethyl)-4-methoxypyridine hydrochloride, there are many other studies that have used 2-(Chloromethyl)-4-methoxypyridine hydrochloride(cas: 62734-08-1Product Details of 62734-08-1) was used in this study.
2-(Chloromethyl)-4-methoxypyridine hydrochloride(cas: 62734-08-1) belongs to pyridine. Pyridine-based materials are valued for their optical and physical properties as well as their medical potential. Additionally, pyridine-based natural products continue to be discovered and studied for their properties and to understand their biosynthesis.Product Details of 62734-08-1
