(Ferrocenylvinyl)arenes 3, 5 , and 7 are obtained from vinylferrocene ( 1 ) and substituted aromatic and heteroaromatic halides by palladium‐catalyzed Heck‐type reactions. Up to three ferrocene units are introduced in one step by the multi‐fold reaction of 1,2‐dibromo‐ ( 4 ) or 1,3,5‐tribromobenzene ( 6 ) with 1. The first crystal structure of a bis(ferrocenylvinyl)benzene chromophore ( 5 ) is reported.
