A highly efficient method for the selective formal C–H/C–H cross-coupling of azoles and (hetero)arenes was established through arylsulfonium intermediates under transition-metal catalysis, which produced a variety of 2-(hetero)aryl azoles in good to excellent yields. Advantages of the reaction included mildness, a good functional group tolerance, a wide range of substrates, a high regio- and chemoselectivity
在过渡金属催化下,通过芳基锍中间体建立了一种用于唑类和(杂)芳烃的选择性形式 C-H/C-H 交叉偶联的高效方法,该方法可以很好地生产各种 2-(杂)芳基唑类化合物。以优异的产量。该反应的优点包括温和、官能团耐受性好、底物范围广、区域选择性和化学选择性高、一锅法以及不使用氧化剂的复杂分子的后期功能化,提供了一种有前景的策略用于过渡金属催化的唑类的 C-H 芳基化。
