1,1'-Bis(diphenylphosphino)ferrocene

1,1'-Bis(diphenylphosphino)ferrocene, commonly abbreviated dppf, is a substituted phosphine commonly used, as are other phosphines, as a ligand in organometallic chemistry. It contains a ferrocene moiety in its backbone, and is closely related to other bridged diphenylphosphines such as 1,1-bis(diphenylphosphino)methane (dppm) and 1,2-bis(diphenylphosphino)ethane (dppe). It is commercially available, and is usually purchased rather than synthesized.
