Pentafluorophenylxenon(II) hexafluoroarsenate [C6F5Xe]+[AsF6]− reacts (MeCN, 20 °C) with aromatic compounds C6H5X (X = CH3, F, CF3, NO2 and CN), yielding isomeric mixtures of polyfluorinated biphenyls XC6H4C6F5. When X = I, iodopentafluorobenzene is formed in addition, whereas trimethylsilylbenzene (X = SiMe3) is only converted to C6H5C6F5 and C6F5H. These results are compared with the data for the
六氟砷酸五氟苯基氙(II)[C 6 F 5 Xe] + [AsF 6 ] -(MeCN,20°C)与芳族化合物C 6 H 5 X(X = CH 3,F,CF 3,NO 2和CN)反应,得到多氟联苯XC 6 H 4 C 6 F 5的异构体混合物。当X = 1时,另外形成碘五氟苯,而三甲基甲硅烷基苯(X = SiMe 3)仅转化为C 6 H 5 C 6 F 5和C。6个˚F 5 H.这些结果与用于与氟化氙相应的芳族化合物的基团和pentafluorophenylation氟化反应的数据相比较2。在以下条件下,多氟芳族化合物C 6 F 6,C 6 F 5 H,C 6 F 5 I,C 6 F 5 CN和C 6 F 5 SiMe 3不与[C 6 F 5 Xe] + [AsF 6 ] -反应。相同的条件。
