A highly efficient and practical heterogeneous palladium-catalyzed carbonylative coupling of 2-iodoanilines with aryl iodides has been developed. The reaction occurs smoothly in toluene at 110 °C with N,N-diisopropylethylamine as base under carbon monoxide (5 bar) and offers a general and powerful tool for the construction of various valuable 2-arylbenzoxazinones with excellent atom-economy, high functional group tolerance, good to high yields, and easy recyclability of the palladium catalyst. The reaction is the first example of heterogeneous palladium-catalyzed carbonylative coupling for the preparation of diverse 2-arylbenzoxazinones from commercially easily available 2-iodoanilines and aryl iodides.

2-碘代苯胺与芳基碘化物的可循环异构钯催化羰基化环化反应，生成2-芳基苯并恶嗪酮
已经开发了2-碘苯胺与芳基碘化物的高效且实用的钯催化的羰基化偶联。该反应在一氧化碳（5 bar）下以N，N-二异丙基乙胺为碱在110°C的甲苯中顺利进行，它为构建具有优异原子经济性，高官能团的各种有价值的2-芳基苯并恶嗪酮提供了一个通用而有力的工具钯催化剂具有良好的耐受性，良好的高收率和易于回收利用的特点。该反应是从市售易得的2-碘苯胺和碘代芳基制备各种2-芳基苯并恶嗪酮的异相钯催化羰基化偶联的第一个实例。
