(1,1'-Bis(diphenylphosphino)ferrocene)palladium(II) dichloride

[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)PdCl2]. This commercially available material can be prepared by reacting dppf with a suitable nitrile complex of palladium dichloride:[1]

dppf + PdCl2(RCN)2  (dppf)PdCl2 + 2 RCN (RCN = CH3CN or C6H5CN)
