1,3-Bis(diphenylphosphino)propane (dppp) is a diphosphine often found as a ligand in coordination chemistry.

The diphosphine can be prepared by the reaction of lithium diphenylphosphide and 1,3-dichloropropane.

2 Ph2PLi + C3H6Cl2 → Ph2PC3H6PPh2 + 2 LiCl

The diphosphine is a precursor to the complex dichloro(1,3-bis(diphenylphosphino)propane)nickel, which is prepared by combining equimolar portions of the ligand and nickel(II) chloride hexahydrate. This nickel complex serves as a catalyst for the Kumada coupling reaction.[1] Dppp is also used as a ligand for palladium(II) catalysts to co-polymerize carbon monoxide and ethylene to give polyketones.[2]
