  通过氧化氧化将白磷直接转化为多功能磷转移试剂

  摘要：

  用于工业和研究的增值磷化学品的主要原料是白磷（P 4），其中形成 P(III) 化合物的关键中间体是 PCl 3。由于其高反应性，基于 PCl 3的合成通常伴随着产物混合物和费力的后处理程序，因此需要一种替代方法来形成可行的 P(III) 转移试剂。我们的氧化氧化概念，其中白磷被选择性地转化为多功能 P 1转移试剂的三氟甲磺酸盐，例如 [P(L N ) 3 ][OTf] 3 (L N是阳离子、N基取代基；即，4-二甲氨基吡啶），为实现 P-O、P-N 和 P-C 键提供了一种方便的替代方案，同时避免了 PCl 3的使用。我们使用 R n E类型的 p 嵌段元素化合物（例如，Ph 3 As 或 PhI）来获得氮路易斯碱 L N和相应的双阳离子 [R n EL N ] 2+之间的弱加合物。[R n EL N ] 2+ + L N和 [R n E(L N ) 2 ] 2+之间的拟议平衡允许 P 4中所有六个
