The formation of the stable phosphonium ions from polyfluoroaromatic phosphines of C6F5PX2 type [X = H, CH3, C6H5, C6F5, Cl, F, NCS, CN, OCH3, N(C2H5)2] in HSO3FSbF5 (1:1) at −70 to −1O°C has been shown, as well as the transformation of the investigated phosphines in HSO3F at 20°C into the pentavalent phosphorus derivatives.The same processes take place also for the trivalent arsenic and antimony
由C 6 F 5 PX 2型[X = H,CH 3,C 6 H 5,C 6 F 5,Cl,F,NCS,CN,OCH 3,N(C 2 ħ 5)2 ]中HSO 3 FSbF 5(1:1)在-70至-10℃的已被示出,以及在HSO的被调查膦的转化3F在20°C时生成五价磷衍生物,三价砷和锑衍生物也进行相同的过程。已经讨论了后者反应的可能途径以及决定因素。在HSO 3中由C 6 F 5 P(OCH 3)2和C 6 F 5 P(CN)2异常形成五氟苯膦酸二氟酸酐的质子化形式已找到F。已证明在-60°C下由强酸中的多氟亚硝基苯生成亚硝酸根阳离子。在相同的介质中于20°C,这些阳离子发生氧化,生成相应的硝基苯。研究了介质酸度对亚硝基苯反应的影响。
