We report ruthenium(II)-catalyzed -C-H arylation of N,N-dialkylthiobenzamides with boronic acids. The method employs [RuCl(-cym)] in the presence of Cu(OTf) and AgO oxidant. The reaction represents the first example of Ru-catalyzed C-H arylation directed by sulfur-containing groups and a rare example of C-H arylation directed by the versatile thiobenzamide moiety. As a further advantage, the method is performed in sustainable and eco-friendly 2-MeTHF as a solvent.
我们报告了钌（II）催化的 N,N-二烷基硫代苯甲酰胺与硼酸的 -C-H 芳基化反应。该方法采用 [RuCl(-cym)]，在 Cu(OTf) 和 AgO 氧化剂的存在下进行。该反应代表了首例由含硫基团导向的 Ru 催化 C-H 芳基化反应，也是由多功能硫代苯甲酰胺部分导向的 C-H 芳基化反应的罕见例子。作为进一步的优点，该方法在可持续且环保的 2-MeTHF 溶剂中进行。
