The challenging nickel‐catalyzed mono‐α‐arylation of acetone with aryl chlorides, pivalates, and carbamates has been achieved for the first time. A nickel/Josiphos‐based catalytic system is shown to feature unique catalytic behavior, allowing the highly selective formation of the desired mono‐α‐arylated acetone. The developed methodology was applied to a variety of (hetero)aryl chlorides including
丙酮与芳基氯化物,新戊酸酯和氨基甲酸酯的具有挑战性的镍催化的单α-芳基化反应已首次实现。镍/ Josiphos基催化体系显示出独特的催化行为,可以高度选择性地形成所需的单α-芳基化丙酮。所开发的方法适用于各种(杂)芳基氯化物,包括生物学相关的衍生物。该方法已扩展到丙酮与苯酚衍生物的空前偶联。机理研究允许分离和表征关键的Ni 0和Ni II催化中间体。已证明Josiphos配体在稳定Ni II中间体以产生Ni 0方面起关键作用/ Ni II催化途径。然后利用对空气稳定的Ni II预催化剂,利用机理上的理解来改进方案。
