Arrhenius parameters have been measured for the reactions of picryl chloride with the following substituted anilines in acetonitrile: 3-amino- and 3-methyl-aniline, 3-amino-5-nitroaniline, 3-fluoro-5-methylsulphonyl-aniline, 3-X-5-methylanilines (X = NO2, OMe, CH3, F, Cl, Br, or I) and 3,5-X2-anilines (X = F, Cl, Br, or I). A total of 33 3,5-disubstituted anilines have now been examined for the additivity
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-氨基和3-甲基苯胺,3-氨基-5-硝基苯胺,3-氟-5-甲基磺酰基苯胺,3- X-5-甲基苯胺(X = NO 2,OMe,CH 3,F,Cl,Br或I)和3,5-X 2-苯胺(X = F,Cl,Br或I)。现已研究了总共33个3,5-二取代苯胺对取代基对活化自由能的可加性的影响,并且表明,除3-氨基-5-硝基苯胺外,该假说重现了实验速率常数。在2分之一的范围内,当使用更严格的可加性标准时,对于某些情况下出现的偏差提出了合理化建议。
