A novel and efficient method for the carbonylative activation of benzotriazoles to benzoxazinones has been developed. By using a silver and palladium bimetallic catalyst system, a broad range of benzotriazoles were transformed into the corresponding benzoxazinones in moderate to good yields with excellent functional group tolerance. Notably, this procedure proceeds under neutral conditions.
