摘要
本文测定了苯甲亚氨酸乙酯(Ⅰ)和N-乙氧基羰基亚甲基苯甲亚氨酸乙酯(Ⅱ)的~1H和^(13)C NMR谱,归属了共振谱线,得到了这两类化合物的官能团在苯衍生物中的经验增量,讨论了化学位移与Hammett常数的相关性.
1H and 13C NMR spectra of ethyl benzenecarboximidates (Ⅰ) and ethyl N -(ethoxycarbonylmethyl) benzenecarboximidates (Ⅱ) were determined. The resonance lines of these compounds were assigned, and the empirical substituent increments of Et were obtained. It was found that there
were some linear relationships between chemical shifts and Hammett constants σ.
