by C–H activation is described. Acetamide was found to be an effective cocatalyst for this generally applicable ruthenium(II)-catalyzed direct arylation reaction. A wide range of deactivated aryl chlorides could be efficiently coupled under the mild temperature of 101 °C. The new process is highly atom-economical and sustainable.
描述了一种通过 C-H 活化交叉偶联芳烃的简单高效的方法。发现乙酰胺是这种普遍适用的钌 (II) 催化的直接芳基化反应的有效助催化剂。在 101 °C 的温和温度下,可以有效地偶联多种失活的芳基氯。新工艺具有高度的原子经济性和可持续性。
