摘　　要：以2-甲基-5-硝基苯磺酸和3,4-二甲氧基苯甲醛为起始原料,经过缩合反应合成未见报道的(E)-2-(3,4-二甲氧基苯乙烯基)-5-硝基苯磺酸钠。通过MS、IR和NMR等技术进行表征,利用1H NMR谱中反式双键、苯环上邻位或间位氢质子耦合常数J以及IR谱中反式双键上C-H弯曲震动产生的特征吸收峰的特点,结合13C NMR谱、135°DEPT谱、HSQC谱、HMBC谱和1H-1H COSY谱进行分析和验证,确定目标化合物的结构,对目标化合物分子中的碳原子、氢原子化学位移进行准确归属和报道。The unreported compound was synthesized from 2-methyl-5-nitrobenzenesulfonic acid and 3,4-dimethoxybenzaldehyde via condensation reaction. The structure of it was determined by HRMS,IR,and NMR spectrum,which has fully characterized by using the characteristics of the trans double bond,the o-position or interposition hydrogen of benzene ring of coupling constant J in the 1H NMR spectrum and the characteristic absorption peaks formed by the bending vibration of IR spectrum of antidouble bond. All accurate chemical shifts were first assigned and reported by 13C NMR spectrum,135°DEPT spectrum,HSQC spectrum,HMBC spectrum and 1H-1H COSY spectrum.
