catalysis is an efficient process for the alkylation of diverse organic compounds via the generation of alkyl radicals from alkyl bromides and iodides. However, the generation of alkyl radicals from more stable alkyl chlorides remains challenging. Herein, we demonstrate the excited-state palladium-catalyzed synthesis of oxindoles and isoquinolinediones via alkylation/annulation reaction by overcoming
激发态钯催化是通过从烷基溴化物和碘化物生成烷基自由基来使各种有机化合物烷基化的有效方法。然而,从更稳定的烷基氯生成烷基自由基仍然具有挑战性。在此,我们通过克服与未活化的 C(sp 3 )-Cl 键在室温下活化相关的固有限制,证明了激发态钯催化合成羟吲哚和异喹啉二酮的烷基化/环化反应。
