possibility to combine oxidative addition of aryl iodides and π‐activation of alkenes at gold is demonstrated for the first time. The reaction is robust and general (>30 examples including internal alkenes, 5‐, 6‐, and 7‐membered rings). It is regioselective and leads exclusively to trans addition products. The (P,N) gold complex is most efficient with electron‐rich aryl substrates, which are troublesome

碘化物的氧化加成和烯烃的π-活化的可能性。该反应牢固且通用(> 30个实例,包括内部烯烃,5元,6元和7元环)。它是区域选择性的,专门导致反式加成产物。(P,N)
金络合物在富电子芳基底物方面效率最高,这对于其他光氧化还原/氧化方法来说是麻烦的。此外,它还提供了从5外向内向6内向区域选择性的非常不同的转换 内部烯醇的Z和E异构体之间的环化。
