Copper-Catalyzed Intramolecular Oxidative CH Functionalization and CN Formation of 2-Aminobenzophenones: Unusual Pseudo-1,2-Shift of the Substituent on the Aryl Ring
A good move: A copper‐catalyzed intramolecular oxidative CH functionalization of 2‐aminobenzophenone affords two regioisomeric acridones (see scheme). The reaction involves an unusual pseudo‐1,2‐migration of R2 group(s) on the arene ring (bpy=2,2′‐bipyridine, DMAc=dimethylacetimide).
