[Bis(trifluoroacetoxy)iodo]perfluoroalkanes C(n)F(2n+1)I(OCOCF(3))(2) (n = 4, 6, 8, 10, 12) can be conveniently prepared by the oxidation of the corresponding perfluoroalkyl iodides with Oxone in trifluoroacetic acid at room temperature and subsequently converted to the stable [hydroxy(tosyloxy)iodo]perfluoroalkanes, C(n)F(2n+1)I(OH)OTs, by treatment with p-toluenesulfonic acid. This general and convenient procedure has been further extended to the synthesis of various [bis(trifluoroacetoxy)iodo]arenes, ArI(OCOCF(3))(2).
[双（三氟乙酰氧基）碘代]全氟烷烃 C(n)F(2n+1)I(OCOCF(3))(2)（n = 4、6、8、10、12）可通过在室温下用 Oxone 在三氟乙酸中氧化相应的全氟碘化物方便地制备，并且随后通过用对甲苯磺酸处理转化为稳定的[羟基（对甲苯磺酰氧基）碘代]全氟烷烃，C(n)F(2n+1)I(OH)OTs。该通用且方便的程序已进一步扩展到各种[双（三氟乙酰氧基）碘代]芳烃，ArI(OCOCF(3))(2)的合成中。
