Arrhenius parameters have been measured for the reactions of picryl chloride with the following substituted anilines in acetonitrile: 3-methoxyaniline, 3-X-5-nitroanilines (X = CF3, SO2Me, or Me), 3-X-5-methoxyanilines (X = F, Cl, Br, I, CF3, SO2Me, or OMe), and 3-X-5-methylsulphonylanilines (X = Cl, Br, or I). In both the methoxyhalogeno- and methylsulphonyl-halogeno-aniline series, the span of the
已测量了氯化吡咯与以下取代的苯胺在乙腈中的反应的Arrhenius参数:3-甲氧基苯胺,3-X-5-硝基苯胺(X = CF 3,SO 2 Me或Me),3-X-5-甲氧基苯胺(X = F,Cl,Br,I,CF 3,SO 2 Me或OMe)和3-X-5-甲基磺酰苯胺(X = Cl,Br或I)。在甲氧基卤代-和甲基磺酰基-卤代-苯胺系列中,速率常数的跨度较小,log A随着活化能的增加而增加。3-甲基磺酰基-5-硝基苯胺和3-甲基磺酰基-,3-甲氧基-,3-三氟甲基-,3-氟-和3-碘-5-甲氧基苯胺中的取代基对活化自由能的影响为不可加。
