A new domino synthesis of 2‐arylbenzoxazinones has been developed by M. Beller and co‐workers. In their Communication on page 12246 ff. , 19 different benzoxazinones were produced in good yields (65–91%) by palladium‐catalyzed carbonylative coupling of commercially available 2‐bromoanilines and (hetero)aryl bromides. The key step of this transformation is the chemoselective carbonylation of the aryl bromide. Moreover, a one‐pot synthesis of 2,3‐diarylquinazolinones was demonstrated exemplarily.
