cascade manner with an aminative cyclization triggered by N−O bond cleavage of an alkene‐tethered oxime ester. Various arenes, including electron‐rich and electron‐poor arenes, and heteroarenes can be employed in the reaction system. Regioselectivity and radical trapping experiments support the involvement of alkyl radical species, which undergo a homolytic aromatic substitution (HAS) to afford the
在铁催化剂存在下,简单芳烃的分子间CH烷基化反应已通过级联方式实现,并通过烯键式肟酯的N-O键断裂引发了胺化环化反应。反应体系中可以使用多种芳烃,包括富电子芳烃和贫电子芳烃,以及杂芳烃。区域选择性和自由基捕获实验支持烷基自由基种类的参与,该烷基自由基种类经过均溶芳族取代(HAS)提供芳基化产物。
