Bring it on! An effective Pd‐catalyzed orthoolefination of various acetanilides has been developed. This transformation has a broadsubstratescope and wide functional‐group tolerability, regardless of the electronic and steric properties of acetanilidesubstrates, providing a straightforward access to highly functionalized arenes.

The development of a new method for the assembly of unsymmetrical carbazoles is reported. The strategy involves the selective intramolecular functionalization of an arene C-Hbond and the formation of a new arene C-Nbond. The substitution pattern of the carbazole product can be controlled by the design of the biaryl amide substrate, and the method is compatible with a variety of functional groups
