An iron-catalyzed remote C(sp )-H amination of alcohols through 1,5-hydrogen atom transfer is developed. This protocol provides a method to generate δ-C(sp )-N bonds from primary, secondary, and tertiary alcohols under mild conditions. A wide substrate scope and a good functional group tolerance are presented. Mechanistic studies show that a LMCT course of an Fe-OR species and a chlorine radical-induced hydrogen abstraction of an alcohol are possible to generate the alkoxy radical intermediate.
发展了一种铁催化的醇的远程 C(sp )-H 胺化反应,通过 1,5-氢原子转移。该方案在温和条件下,为从伯、仲和叔醇生成 δ-C(sp )-N 键提供了一种方法。该方法具有广泛的底物范围和良好的官能团耐受性。机理研究表明,Fe-OR 物种的 LMCT 过程和氯自由基诱导的醇的氢提取可能生成烷氧基自由基中间体。
