| 中文摘要: |
| 合成了三种苄基咪唑氯镍酸盐,通过红外光谱、元素分析、核磁共振(1H NMR)以及X-射线单晶衍射对其结构进行了表征,并研究了其在醛醇酯化反应中的催化活性。催化研究结果表明,在优化条件下,苄基咪唑氯镍酸盐对醛醇酯化反应有着较好的催化活性,以对甲基苄基咪唑氯镍酸盐为催化剂,通过一步氧化酯化路线可以有效地催化氧化苯甲醛进行酯化反应,产率为80 %。 |
| 英文摘要: |
| Three tetrachloronickelate benzylimidazolium salts were synthesized and characterized by IR spectroscopy, elemental analysis, nuclear magnetic resonance, and single crystal X-ray diffraction analysis. Further more, the compounds were tested as catalysts for oxidative esterification of aldehydes with alcohol. The experimental results showed that tetrachloronickelate benzylimidazolium salt exhibited high catalytic activity in oxidative esterification reaction. Under the optimal reaction conditions, the yield of methyl benzoate can reach up 80 % when using 4-methylbenzylimidazolium tetrachloronickelate as catalyst. |
