for site‐selective functionalization of unactivated methylene and methine C−H bonds enabled by an FeII‐catalyzed redox process is described. The mild, expeditious, and modular protocol allows efficient remote aliphatic fluorination, chlorination, amination, and alkynylation of structurally and electronically varied primary, secondary, and tertiary hydroperoxides with excellent functional‐group tolerance
描述了一种通过Fe II催化的氧化还原过程实现未活化的亚甲基和次甲基CH键的位点选择性官能化的烷氧基自由基导向策略。温和,快捷和模块化的协议允许对结构和电子形式不同的伯,仲和叔氢过氧化物进行高效的远程脂肪族氟化,氯化,胺化和炔基化反应,并具有出色的官能团耐受性。还演示了由有氧CH氧化引发的非氧化烷烃底物的单锅1,4-羟基官能化的应用。
