In this communication, we disclosed a palladium-catalyzed carbonylative procedure for the synthesis of 1-aroyl-3-aryl-1,5-dihydro-2H-pyrrol-2-ones from propargyl amines and aryl halides. By using TFBen as the CO source, the reaction provides a facile and straightforward access to various aryl-substituted 2-oxo-2,5-dihydropyrroles in good yields. The reaction mechanism is proven to be attractive as well.

炔丙基胺和芳基卤化物的钯催化双羰基化反应，以生成1-芳基-3-芳基-1,5-二氢-2H-吡咯-2-酮

在此文中，我们公开了由炔丙基胺和芳基卤化物合成1-芳基-3-芳基-1,5-二氢-2 H-吡咯-2-酮的钯催化羰基化方法。通过使用TFBen作为CO源，该反应以高收率容易且直接地获得各种芳基取代的2-氧代-2，5-二氢吡咯。反应机理也被证明是有吸引力的。
