  摘要：

  季phospho盐（QPS）是一类重要的有机磷化合物，以前只能通过涉及亲核性磷的途径获得。我们报告了利用膦氧化物作为亲电子伴侣和格氏试剂作为亲核试剂实现QPS的相反方法的实现。通过衍生的卤化salts盐的关键中间体来实现该过程。该路线不受动力学慢和许多母体膦的有限供应的困扰，并且以优异的产率制备了多种QPS。

  phosphonium salts R3PR1 X (X = Cl, Br) from phosphine oxides R3PO. The new organic group R1 is introduced via nucleophilic attack on an intermediate halophosphonium salt using a Grignard reagent R1MgX and replaces the traditional phosphine quaternization approach. Consequently, the new method does not suffer from the limited availability of many parent phosphines and is much faster than standard quaternization

  摘要 我们提出了一种新的、潜在广泛适用的 Umpolung 方法，用于从氧化膦 R3PO 合成季鏻盐 R3PR1 X (X = Cl, Br)。新的有机基团 R1 是通过使用格氏试剂 R1MgX 对中间卤代鏻盐进行亲核攻击引入的，并取代了传统的膦季铵化方法。因此，新方法不会受到许多母膦的有限可用性的影响，并且比标准季铵化要快得多。图形概要
