The activation and utilization of substrates mediated by Frustrated Lewis Pairs (FLPs) was initially believed to occur solely via a two-electron, cooperative mechanism. More recently, the occurrence of a single-electron transfer (SET) from the Lewis base to the Lewis acid was observed, indicating that mechanisms that proceed via one-electron-transfer processes are also feasible. As such, SET in FLP systems leads to the formation of radical ion pairs, which have recently been more frequently observed. In this review, we aim to discuss the seminal findings regarding the recently established insights into the SET processes in FLP chemistry as well as highlight examples of this radical formation process. In addition, applications of reported main group radicals will also be reviewed and discussed in the context of the understanding of SET processes in FLP systems.

深入研究受挫路易斯对化学中的单电子转移过程以及主族化学中的相关供体-受体系统

受阻路易斯对 (FLP) 介导的底物的激活和利用最初被认为仅通过双电子协作机制发生。最近，观察到从路易斯碱到路易斯酸的单电子转移（SET）的发生，表明通过单电子转移过程进行的机制也是可行的。因此，FLP 系统中的 SET 会导致自由基离子对的形成，最近这种情况被更频繁地观察到。在这篇综述中，我们的目的是讨论最近对 FLP 化学中 SET 过程的深入见解的开创性发现，并重点介绍这种自由基形成过程的例子。此外，还将在理解 FLP 系统中的 SET 过程的背景下回顾和讨论已报道的主族自由基的应用。
