含有吸电子基团的二硝基苯类化合物反应活性明显高于含有供电子基的二硝基化合物的加氢反应；
The dinitrobenzene with electron-withdrawing group can be hydrogenated much easier than the dinitrobenzene with electron-donating group.
研究发现，无论对于吸电子取代基还是供电子的取代基对烯基亚砜的活性都没有任何影响，而邻甲基苯醌前体化合物中所带有的吸电子基团能增加其反应活性。
It was found that both the electro-withdraw and electro-donating substituents have no effect on reaction activity and the electro-withdraw substituents can increase the reaction activity.
