文章报道并研究了十九个新的不对称取代乙二胺及其衍生物的￣１Ｈ－ＮＭＲ，发现此类化合物中连二亚甲基的化学位移存在递变规律，指出该规律与其相连氮上的取代基的共轭效应和诱导效应的强弱相关。
The article reported and studied the nineteen new asymmetric substitution of ethylenediamine and its derivatives ~ 1H-NMR and found that there is a gradual change in the chemical shift of the dienophile in such compounds, pointing out that the law associated with its nitrogen The conjugation effects on the substituents are related to the induction effect.
