1,1'-Bis(diphenylphosphino)ferrocene, commonly abbreviated dppf, is an organophosphorous compound commonly used as a ligand in homogeneous catalysis. It contains a ferrocene moiety in its backbone, and is related to other bridged diphosphines 1,2-bis(diphenylphosphino)ethane (dppe).
- Fe(C5H4Li)2 + 2 ClPPh2 → Fe(C5H4PPh2)2 + 2 LiCl
The dilithiation of ferrocene is easily achieved with n-butyllithium in the presence of TMEDA. Many related ligands can be made in this way. The Fe center is typically not involved in the behavior of the ligand.
Dppf readily forms metal complexes. The palladium derivative, (dppf)PdCl2, which is popular for palladium-catalyzed coupling reactions, is prepared by treating dppf with the acetonitrile or benzonitrile adducts of palladium dichloride:
