Acetamide as Cocatalyst for the Nitrogen-Directed Coupling of Arenes with Aryl Chlorides through Ruthenium-Catalyzed C–H Activation



A simple and highly efficient method for the cross-coupling of aromatics 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.
