cross-couple unactivated secondary alkyl iodides with various N-, O-, and C-based nucleophiles. This strategy harnesses the ability of photoredox-generated phenyl radicals to mediate halogen-atom transfer (XAT) and convert alkyl iodides into the corresponding radicals. These species engage in a second catalytic cycle, mediated by copper, which enables C–N/O/C bond formation with the various nucleophiles
在这里,我们报告了一种工具箱策略,用于将未活化的仲烷基碘与各种基于 N、O 和 C 的亲核试剂交叉偶联。该策略利用光氧化还原产生的苯基自由基介导卤素原子转移 (XAT) 并将烷基碘转化为相应自由基的能力。这些物质参与由铜介导的第二个催化循环,从而能够与各种亲核试剂形成 C-N/O/C 键。
