  摘要：

  Abstractmagnified imageThe intermolecular three‐component coupling of aryl iodides, diarylacetylenes, and alkenes effectively proceeds in the presence of palladium acetylacetonate and silver acetate as catalyst and base, respectively, to give the corresponding 1:2:1 coupling products, 1,3,5‐hexatriene derivatives. A further homologation of the oligoene chain of the three‐component coupling products by a simple procedure is also presented.
