Herein, we describe the development of a copper-catalyzed C(sp3) amination of unactivated secondary alkyl iodides mediated by diaryliodonium salts. Our protocol is enabled by the intermediacy of aryl radical species that undergo halogen atom transfer prior to interfacing with copper catalysts, thus setting the basis for a C–N bond formation at sp3-hybridized carbons. The method is characterized by
在此,我们描述了由二芳基碘盐介导的未活化仲烷基碘的铜催化 C(sp 3 ) 胺化反应的发展。我们的协议是通过在与铜催化剂连接之前经历卤素原子转移的芳基自由基物种的中介作用实现的,从而为在 sp 3 -杂化碳上形成 C-N 键奠定了基础。该方法具有反应条件温和、区域选择性好、底物适用范围广等特点。
