1,3-Bis(diphenylphosphino)propane (dppp) is an organophosphorus compound with the formula Ph2P(CH2)3PPh2. The compound is a white solid that is soluble in organic solvents. It is slightly air-sensitive, degrading in air to the phosphine oxide. It is classified as a diphosphine ligand in coordination chemistry and homogeneous catalysis. The diphosphine can be prepared by the reaction of lithium diphenylphosphide and 1,3-dichloropropane (Ph = C6H5): 2 Ph2PLi + C3H6Cl2 → Ph2P(CH2)3PPh2 + 2 LiCl
