1,1'-Bis(diphenylphosphino)ferrocene is deep yellow crystalline powder

1,1'-Bis(diphenylphosphino)ferrocene acts as a ligand in homogeneous catalysis. It is used as a ligand for ruthenium-catalyzed greener amine synthesis from amines and alcohols by hydrogen-borrowing. It is also employed as a ligand for Buchwald-Hartwig cross coupling. Further, it is used in the synthesis of coordination compound as well as the formation of complexes with various metals such as palladium chloride. In addition to this, it serves as a reagent for palladium-catalyzed coupling reactions and also plays an important role in Suzuki reaction.

1,1'-Bis(diphenylphosphino)ferrocene used coordination compound in synthesis, readily forms complexes with various metals, i.e. when reacting with the acetonitrile or benzonitrile complexes of PdCl2 it forms (dppf)PdCl2, which i s a popular reagent for palladium-catalyzed coupling reactions.

Novel functionalized furan derivatives were prepared via Pd-phosphine sequential C-C and C-O bond formation.

Wash it with distilled H2O and dry it in a vacuum. Dissolve it in ca 5 parts of hot dioxane and cool to give orange crystals m 181-183o. Recrystallisation from *C6H6/heptane (1:2) gives a product with m 183-184o. [Bishop et al. J Organomet Chem 27 241 1971.]
