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

rdfs:comment	1,3-Bis(diphenylphosphino)propan (abgekürzt: dppp) ist eine organische Verbindung. Sie wird als Ligand für katalytisch aktive Komplexe eingesetzt. (de) Il 1,3-bis(difenilfosfino)propano è una fosfina con formula Ph2P-CH2-CH2-CH2-PPh2 (Ph = fenile). Il nome è generalmente abbreviato come dppp. In condizioni normali è un solido di colore bianco sensibile all'ossigeno atmosferico. Viene comunemente usato come legante bidentato in chimica inorganica e chimica metallorganica. Il dppp funziona nella maggior parte dei casi come legante chelato, ma può fare anche da legante a ponte tra due metalli. (it) 1,3-ビス (ジフェニルホスフィノ) プロパン (1,3-Bis(diphenylphosphino)propane = dppp) は、化学式 Ph2P(CH2)3PPh2 で表される有機リン化合物である。白色の固まりで有機溶媒に溶ける。やや空気の影響を受けやすく、空気中でホスフィンオキシドに分解する。配位化学および均一系触媒ではジホスフィン配位子に分類される。 1,3-ビス (ジフェニルホスフィノ) プロパンは、リチウムジフェニルホスフィドとの反応によって調製できる。 (Ph = C6H5): 2 Ph2PLi + C3H6Cl2 → Ph2P(CH2)3PPh2 + 2 LiCl しかし、金属-ハロゲン交換とメタセシスを介して、はるかに制御可能な (かつ安価な) ルートで合成できる。 Br(CH2)3Br + 2 tBuLi → Li(CH2)3Li + 2 tBuBrLi(CH2)3Li + 2 PCl3 → Cl2P(CH2)3PCl2 + 2 LiClCl2P(CH2)3PCl2 + 4 PhLi → Ph2P(CH2)3PPh2 + 4 LiCl (ja) 1,3-Bis(difenylfosfino)propaan, vanuit het Engels vaak afgekort tot dppp (1,3-Bis(diphenylphosphino)propane) is een difosfine dat in de anorganische chemie vaak als ligand gebruikt wordt. De stof kan gesynthetiseerd worden uit en 1,3-dichloorpropaan: Een tweede syntheseroute gaat uit van difenylfosfine en 1,3-dibroompropaan in aanwezigheid van een base. Onder andere cesiumhydroxide is voor dit doel toegepast. De base deprotoneert het fosfine, dat vervolgens een nucleofiele substitutie uitvoert op het broomalkaan.
