Abstract
2-Electron-withdrawing-group-substituted 2-bromoanilides can be converted to the corresponding 3,3-disubstituted oxindoles with high efficiency under visible light irradiation by using fac-Ir(ppy)(3) as the photoredox catalyst. This protocol is suitable for the synthesis of oxindoles with chloro and bromo atoms attached to the phenyl ring.
摘要
2-溴代邻苯二甲酰亚胺经可见光照射，以 fac-Ir(ppy)3 为光催化剂，可高效转化为相应的 3,3-二取代的色酮。该反应适用于在苯环上连有氯原子和溴原子的色酮的合成。
