activation and transformation. However, direct PCET activation of nonpolar bonds such as the C–H bond, O2, and N2 has yet to be explored. Herein, we report that the interaction between electron donor and proton donor could overcome the barrier of direct O2 activation via a concerted electron–proton transfer mechanism. This work provides a new strategy for developing direct PCET activation of nonpolar bonds
质子耦合电子转移(PCET)反应因其在化学、生物学和材料科学中的广泛存在而受到广泛关注。通过酪氨酸和苯酚氧化等模型体系的机理研究逐渐加深了对PCET反应的认识,并被广泛接受并应用于键的活化和转化。然而,对非极性键如 C-H 键、O 2和 N 2的直接 PCET 活化仍有待探索。在此,我们报告电子供体和质子供体之间的相互作用可以通过协同的电子-质子转移机制克服直接O 2活化的障碍。这项工作为开发非极性键的直接 PCET 活化提供了新的策略。
