Herein, we describe the formation of an electron donor–acceptor (EDA) complex between electron-rich cycloalkanols and electron-deficient alkenes that triggers the proton-coupled electron transfer ring opening of strained and unstrained cycloalkanols without the need for an external photocatalyst. This activation generates a remote alkyl radical that undergoes a Giese reaction with the Michael acceptor
在此,我们描述了富电子环烷醇和缺电子烯烃之间形成电子供体-受体(E
DA)络合物,该络合物触发应变和非应变环烷醇的质子耦合电子转移环打开,而不需要外部光催化剂。这种激活产生一个远程烷基自由基,该烷基自由基以有效的方式与迈克尔受体发生吉斯反应。机理研究证实了 E
DA 复合物的形成和连续的 Giese 反应。
