本文介绍了一个新的王冠化合物4-甲基-5-溴代苯并-15-冠-5的合成方法,对合成的稀土硝酸盐冠醚配合物进行了元素分析、差热分析、可见和紫外光谱、红外光谱和~1H核磁共振谱的测定,由红外数据推测配合物中的中心离子的配位数为11。
In this paper, a new synthesis method of crown compound 4-methyl-5-bromobenzo-15-crown-5 was introduced. Elemental analysis and differential thermal analysis of the synthesized rare earth nitrate crown ethers were carried out. UV spectroscopy, infrared spectroscopy and ~ 1H nuclear magnetic resonance spectroscopy, the infrared data suggest that the complex coordination number of the central ion 11.
