The reactions of elemental phosphorus, arsenic and antimony with sodium metal in liquid ammonia form “M−1“ species that react with haloarenes under irradiation to form symmetrical triaryl derivatives of these metals by the SRN1 mechanism in fair to good yields. Further reaction with sodium metal gives a derivative nucleophile (diarylphosphide and diarylarsenide ions) that reacts with another haloarene
元素磷,砷和锑与液态氨中的钠金属的反应形成“ M -1 ”物质,这些物质在照射下与卤代芳烃反应,通过S RN 1机理形成这些金属的对称三芳基衍生物,收率相当好。与钠金属进一步反应,得到衍生物的亲核试剂(二芳基磷化物和二芳基砷化物离子),在辐射下与另一种卤代芳烃反应形成不对称的膦和and。
