An approach for the synthesis of benzofulvenes has been developed through palladium‐catalyzed sequential three‐component reactions. The reactions likely involve C,C‐palladacycles as the key intermediates. The palladacycles are generated through cascade reactions of aryl halides and alkynes, and then reacted with CH₂Br₂ to form benzofulvenes as the final products.

钯催化顺序三组分反应合成苯并富烯

通过钯催化的连续三组分反应，已经开发出一种苯并富烯的合成方法。反应可能涉及C，C- palladacycles作为关键中间体。Palladacycles是通过芳基卤化物和炔烃的级联反应生成的，然后与CH ₂ Br ₂反应形成苯并富勒烯作为最终产物。
