scalable synthetic route to both primary arylphosphines ArPH2 and aryldichlorophosphines ArPCl2 is reported. The C–P bond formation was performed in a highly regiospecific manner through electrophilicsubstitution of selected aromatic hydrocarbons (ArH) with phosphorus pentasulfide. The resultant perthiophosphonic anhydrides Ar2P2S4 were then reacted with LiAlH4 to give primary phosphines ArPH2. Subsequent
报道了伯芳基膦 ArPH 2和芳基二氯膦ArPCl 2的可扩展合成路线。通过用五硫化二磷对选定的芳烃 (ArH) 进行亲电取代,以高度区域特异性的方式形成 C-P 键。然后将所得的过硫代膦酸酐Ar 2 P 2 S 4与LiAlH 4反应以得到伯膦ArPH 2。随后 ArPH 2与光气溶液反应生成二氯膦 ArPCl 2. 每个反应步骤都需要最少的纯化,并使用市售且经济的前体。反应的范围显示包括烷氧基和苯氧基取代的苯以及萘和芴作为起始原料。
