【摘要】 通过亲核取代反应、Suzuki偶联反应和关环反应合成了二苯并噻吩衍生物,并运用核磁共振（NMR）技术(¹H NMR,¹³C NMR,¹H-¹H COSY,HSQC,HMBC)研究其结构,且报道了其波谱峰位的归属。通过该实验,学生可以比较完整、系统地了解有机合成的主要步骤与表征方法,并且通过分析NMR谱图,理解核磁共振技术在有机合成中确定未知物的重要作用。更多还原

【Abstract】 New dibenzothiophene derivative was synthesized,and the chemical structure was studied by NMR(¹ H NMR,¹³ C NMR,¹ H-¹ H COSY,HSQC,HMBC) techniques. The NMR signals assignment of the target compound were discussed and summarized. Preparation and characterization of a new compound are one of the compulsory experimental courses for the materials science related field student. Consequently,by the experiment,the students can master the main steps and characterization methods of organic synthesis,and realize the important role of nuclear magnetic resonance technique in determining the structure of new compound.更多还原
