on the properties of some 1,2,4-trisubstituted benzenes, the rates of reaction of a series of four 4-substituted 1,2-dinitrobenzenes with sodium methoxide in methanol have been studied. Although reactivities at the 2-position were qualitatively in the order to be expected from inductive effects, those at the 1-position were highly sensitive to the influence of mesomeric donor action of the 4-substituent
为了研究“通过共轭”对某些1,2,4-三取代苯的性质的影响,已经确定了一系列四个4-取代的1,2-二硝基苯与甲醇钠在甲醇中的反应速率。研究过。尽管在2位反应性的定性顺序是从诱导效应中预期的,但在1位反应性对4取代基的介晶供体作用的影响高度敏感。对于4-烷基衍生物,观察到相对较大的影响。C–H高共轭似乎比C–C高共轭强。
