3-二乙胺基丙胺锌配合物的合成及催化活性

Synthesis of Zinc Complex Bearing 3-(Diethylamino)Propylamine Ligand and Its Catalytic Activity

3-二乙胺基丙胺和醋酸锌反应合成了一种新型锌金属配合物,通过红外光谱、核磁氢谱和元素分析等对其结构进行了表征。研究其在催化芳醛和硝基甲烷反应方面的性能,考察了溶剂、催化剂用量、三乙胺和催化剂重复使用性等因素对反应的影响。结果表明:以甲醇为溶剂、催化剂的用量比为12mol%,锌金属配合物在三乙胺的辅助下具有良好的催化性能;并且,催化剂在经过5次使用后,依然能以高于70%的产率得到相应的B-硝基醇产物。

A novel zinc metal complex was synthesized by the reaction of 3-（diethylamino） propylamine to zinc acetate. The structure of the complex was characterized by IR, 1H NMR and elemental analysis. The catalytic activity of the complex for the reaction of aromatic aldehyde to nitromethane was studied, and the influences of solvent, catalyst loading, triethylamine and catalyst reuse cycle on the reaction were surveyed. The results showed that the zinc complex exhibited a good catalytic performance with the assistance of triethylamine in the following conditions：the solvent was methanol and the catalyst loading was 12mol%. What was more, the yields of the β-nitroaleohol products were beyond 70% after tile ealalyst was repeated about 5 times.
