Rhodium-Catalyzed Alkenylation of C-H Bonds in Aromatic Amides with Alkynes.

The rhodium-catalyzed alkenylation of C-H bonds of aromatic amides with alkynes is reported. A variety of functional groups, including OMe, OAc, Br, Cl, and even NO2, are applicable to this reaction to give the corresponding hydroarylation products. The presence of an 8-aminoquinoline group as the directing group is crucial for the success of the reaction.
