Palladium‐Catalyzed Regioselective <i>peri</i>‐ and <i>ortho</i>‐Halogenation of 1‐Naphthaldehydes: Application to the Synthesis of Polycyclic Natural Product Skeletons
an imine formation was necessary to achieve C2-halogenation. The mechanism as well as the regioselectivity of the reaction were studied and the halogenated products were used in the synthesis of natural product skeletons.

We describe a palladium-catalyzed nondirected late-stage deuteration of arenes. Key aspects include the use of D2O as a convenient and easily available deuterium source and the discovery of highly active N,N-bidentate ligands containing an N-acylsulfonamide group. The reported protocol enables high degrees of deuterium incorporation via a reversible C–Hactivation step and features extraordinary functional
