| 摘 要： | 以氧化铍、浓硫酸和乙酰丙酮为原料合成了乙酰丙酮铍。采用X射线衍射、元素分析、紫外-可见吸收光谱、核磁共振氢谱、红外吸收光谱等方法对所合成样品进行表征。结果表明:铍离子与乙酰丙酮根形成螯合环结构;在乙酰丙酮铍中存在两种效应,即金属铍离子的强吸电子效应和螯合环的环电子流效应。此外,环内构成的离域大π键,增加了该化合物的稳定性。

| Abstract: | Beryllium acetylacetonate has been synthesized using beryllium oxide,concentrated sulfuric acid and acetylacetone as starting materials. The product was characterized by powder X-ray diffraction,elemental analysis,UV-visible absorption spectroscopy,Fourier transform infrared spectroscopy,and 1H nuclear magnetic resonance spectroscopy. The results showed that the strong electron-withdrawing effect of Be2+ and the ring current of the chelate ring were both clearly observed. The chelate ring formed between Be2... |
