Cationic cyclopentadienyl iron complexes of substituted phenylenes [CpFe(p-CH₃-C₆H₄-Ar)]PF₆ and [CpFe(p-Ar-C₆H₄-Ar)]PF₆ were obtained in 37–73% yields by Pd-catalyzed Suzuki coupling reactions of [CpFe(p-CH₃-C₆H₄-Cl)]PF₆ and [CpFe(p-Cl-C₆H₄-Cl)]PF₆ with polyarylboronic acids Ar-B(OH)₂ (Ar = biphenyl, naphthyl, phenanthryl, bithienyl). The complex [CpFe(p-CH₃-C₆H₄-Cl)]PF₆ also underwent Sonogashira-type coupling with phenylacetylene to give the compound [CpFe(p-CH₃-C₆H₄-C≡C-Ph]PF₆ in 26% yield. Such coupling reactions represent an alternative approach to [CpFe(arene)]PF₆ complexes, which are typically obtained from ferrocene via Bolesova-Nesmeyanov reaction under harsh conditions (AlCl₃, >100 °C). The structures of the products of Suzuki reaction were established by single-crystal X-ray diffraction analysis.

取代亚苯基[CpFe（p -CH ₃ -C ₆ H ₄ -Ar）] PF ₆和[CpFe（p -Ar-C ₆ H ₄ -Ar）] PF _6的阳离子环戊二烯基铁络合物的含量为37-73％通过钯催化的[CpFe（p -CH ₃ -C ₆ H ₄ -Cl）] PF ₆和[CpFe（p -Cl-C ₆ H ₄ -Cl）] PF ₆与聚芳基硼酸Ar-的Suzuki偶联反应产生乙（OH）₂（Ar ＝联苯，萘基，菲基，联苯二基）。络合物[CpFe的量（p -CH ₃ -C ₆ H ^ ₄ -Cl）] PF ₆也经历Sonogashira类与苯乙炔偶联得到化合物[CpFe的量（对- CH ₃ -C ₆ H ^ ₄ -C ≡C-PH ] PF _6的收率为26％。这种偶联反应代表了[CpFe（arene）] PF ₆络合物的另一种方法，该络合物通常是在苛刻条件下通过Bolesova-Nesmeyanov反应从二茂铁中获得的（AlCl ₃，> 100°C）。通过单晶X射线衍射分析确定了铃木反应产物的结构。
