position‐selective polyhalogenation of aliphatic hydrocarbon bonds is presented. The reaction proceeded within the Hofmann‐Löffler manifold with amidyl radicals as the sole mediators to induce selective 1,5‐ and 1,6‐hydrogen‐atom transfer followed by halogenation. Multiple halogenation events of up to four innate C−H bond functionalizations were accomplished. The broad applicability of this new entry into polyhalogenation
介绍了一种创新的脂族烃键位置选择性多卤化方法。该反应在Hofmann-Löffler流形中进行,酰胺基是唯一的介体,诱导选择性1,5-和1,6--氢原子转移,然后进行卤化。完成了多达四个固有CH键功能化的多次卤化事件。对于总共27个不同的实例(包括混合卤代),证明了这种新进入多卤代反应的广泛适用性以及由此产生的合成可能性。
