[1,1'‑Bis(diphenylphosphino)ferrocene]palladium(II) dichloride is a palladium complex containing the bidentate ligand 1,1'-bis(diphenylphosphino)ferrocene (dppf), abbreviated as [(dppf)PdClШаблон:Sub]. This commercially available material can be prepared by reacting dppf with a suitable nitrile complex of palladium dichloride:[1]

dppf + PdClШаблон:Sub(RCN)Шаблон:Sub → (dppf)PdClШаблон:Sub + 2 RCN (RCN = [[acetonitrile|CHШаблон:SubCN]] or [[benzonitrile|CШаблон:SubHШаблон:SubCN]])

The compound is popularly used for palladium-catalyzed coupling reactions,[2][3] such as the Buchwald–Hartwig amination[4] and the reductive homocoupling of aryl halides.[5]
