Abstract
Cyclopentadiene and metallocenes, typically zirconocene dichloride, are suitable substrates for multiple arylations with aryl bromides in palladium‐catalyzed reactions. Thus, various aryl bromides bearing either an electron‐donating or an electron‐withdrawing substituent can react with these substrates to afford the corresponding 1,2,3,4,5‐pentaaryl‐1,3‐cyclopentadienes in a single preparative step. Derivatives of cyclopentadiene, including di‐ and trisubstituted cyclopentadienes, and indene are arylated in a similar fashion.Keywords
