intermolecular radical insertion of isocyanides to electron-deficient o-alkenylanilines leading to isoindolinone is reported. Deuterium (D2O) and H2O18 labelling experiments suggest H and O incorporation in the product. The formation of an N-centered radical (NCR) via stepwise PT/ET process was confirmed by radical trapping experiments, photoluminescence, cyclic voltammetry and DFT studies. This photo cascade methodology
报道了可见光介导的异氰化物分子间自由基插入到缺电子的o-烯基苯胺,导致异吲哚啉酮。氘 (D 2 O) 和 H 2 O 18标记实验表明产品中含有 H 和 O。通过自由基捕获实验、光致发光、循环伏安法和 DFT 研究证实了通过逐步 PT/ET 过程形成N中心自由基 (NCR) 。这种光级联方法总体上是一种氧化还原中性工艺,具有无金属条件和广泛的基材范围(32 个示例)。GABA 受体拮抗剂类似物的合成显示了该方法的实用性。
