合成

二苯基氯化膦在工業上可由苯和三氯化磷反應得到。反應在600 °C的高溫發生，先生成苯基二氯化膦和HCl，然後二氯化物在氣相經重分配反應得到二苯基氯化膦。^[3]^[4]

2 PhPCl₂ → Ph₂PCl + PCl₃

以三苯基膦和三氯化磷的反應也能得到產物：

PCl₃ + 2 PPh₃ → 2 Ph₂PCl

二苯基氧化膦和乙酰氯在四氫呋喃中反應，也能得到二苯基氯化膦。^[5]

反應

二苯基氯化膦遇水分解。它可以被過氧化氫氧化，生成二苯基膦酸。^[2]它可以被五氟氯化硫氧化，得到二苯基三氟化磷；^[6]它被氯氧化得到二苯基三氯化磷：^[7]

Ph₂PCl + Cl₂ → Ph₂PCl₃

它和甲醇反應，生成二苯基甲氧基膦。^[8]它和2-乙炔基吡啶在三乙胺存在下、碘化亞銅催化下於甲苯中加熱反應，得到2-吡啶基乙炔基二苯基膦。^[9]

用途

二苯基氯化膦可用於合成其它膦類化合物，一種方法是使用格氏試劑：^[4]

Ph₂PCl + MgRX → Ph₂PR + MgClX

反應中生成的膦可進一步用於殺蟲劑（如苯硫磷（英語：EPN (insecticide)））、塑料穩定劑（Sandostab P-EPQ）、鹵素化合物催化劑、阻燃劑（環膦酰羧酸酐）及紫外線硬化塗料體系（用於牙科材料）的合成，這使Ph₂PCl成為重要的反應中間體。^[3]^[4]

二苯基膦基化合物前體

二苯基氯化膦可用作二苯基膦基化合物合成的前體，它和金屬鈉在1,4-二氧六環中回流反應，可以製得二苯基膦基鈉。^[10]

Ph₂PCl + 2 Na → Ph₂PNa + NaCl

它和過量的氫化鋁鋰反應，可以得到二苯基膦。^[11]

4 Ph₂PCl + LiAlH₄ → 4 Ph₂PH + LiCl + AlCl₃

以上兩種二苯基膦化合物都可用於合成其它有機膦配體。^[12]^[13]
