化合物问答
(R)-(6,6′-二甲氧基联苯-2,2′-二基)二[双(3,4,5-三甲氧基苯基)膦](CAS号：256390-47-3)通常如何合成？
答案
![(6,6'-Dimethoxy-2,2'-biphenyldiyl)bis[bis(3,4,5-trimethoxyphenyl)phosphine]](https://cnstatic.chemtradehub.com/structs/256/256390-47-3-d150.webp "(6,6'-Dimethoxy-2,2'-biphenyldiyl)bis[bis(3,4,5-trimethoxyphenyl)phosphine]")
该化合物通常通过先合成3,4,5-三甲氧基苯基膦，然后将两种3,4,5-三甲氧基苯基膦与6,6′-二甲氧基联苯-2,2′-二基二氯化物在合适的溶剂中进行偶联反应合成。常用的催化剂有Pd(PPh3)4，产率约为75%。
