Oxidative anion metatheses in the crude title iodides and chlorides produced the corresponding pure hydrogensulfates, nitrates, tetrafluoroborates, triflates, tosylates, as well as bromides and chlorides (only from the iodides) in 54—86% yields. These procedures are easier and shorter than earlier methods. By using modified oxidative metatheses in the title iodides (in the presence of HBr or HCl) it was possible either to isolate, or to detect only, the intermediate dihaloiodates(I), [Ar2I]+[IX2]− (X = Br or Cl). A complex Ph2I+Cl−·1/2I2 was also obtained in 56% yield. Tetraethylammonium iodide was similarly converted into pure tetrafluoroborate or dibromoiodate(I) in 75 and 76% yields, respectively.

碘化物中使用改进的氧化交换反应(在HBr或HCl存在下),可以分离出中间体二卤离子化
铟(I),[Ar2I]+[IX2]−(X = Br或Cl),或者仅检测到它。同样获得了复杂的Ph2I+Cl−·1/2I2,产率为56%。
四乙基铵碘化物也以类似方式转化为纯四
氟硼酸盐或二
溴离子化
铟(I),产率分别为75%和76%。
