Carbonylation reactions have been widely used in organic synthesis. However, the manipulation of toxic and pressurized carbonmonoxide limited their applications in organic laboratories. The search for alternative carbonyl sources as an important method for carbonylative organic synthesis is spreading. Herein, a series of substituted benzoxazinones were synthesized from N-(o-bromoaryl)amides by palladium-catalyzed
