1,1'-Bis(diphenylphosphino)ferrocene

|Section2=

}}
1,1'-Bis(diphenylphosphino)ferrocene, commonly abbreviated dppf, is an organophosphorus compound commonly used as a ligand in homogeneous catalysis. It contains a ferrocene moiety in its backbone, and is related to other bridged diphosphines such as 1,2-bis(diphenylphosphino)ethane (dppe).
==Preparation==
This compound is commercially available. It may be prepared by treating dilithioferrocene with chlorodiphenylphosphine:
: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.
