This work describes Ni-catalyzed cross-electrophile coupling of benzyl chloroformate derivatives with aryl iodides that generates a wide range of diaryl methane products. The mild reaction conditions merit the C–O bond radical fragmentation of benzyl chloroformates via halide abstraction or a single electron reduction by a Ni catalyst. This work offers a new substrate type for cross-electrophile couplings
这项工作描述了镍催化的氯甲酸苄酯衍生物与芳基碘化物的交叉亲电子偶联,生成多种二芳基甲烷产物。温和的反应条件使得氯甲酸苄酯的 C-O 键自由基通过卤化物夺取或 Ni 催化剂的单电子还原而断裂。这项工作为交叉亲电子偶联提供了一种新的底物类型。
