脂肪胺铜配合物催化合成1-苯基-2-硝基乙醇

Catalytic Synthesis of 1-Phenyl-2-nitroethanol by Copper Complex Containing Aliphatic Amine Ligand

合成了以3-二乙胺基丙胺为配体的新型铜金属配合物,通过元素分析和红外光谱对其结构进行了表征。将其用于催化苯甲醛与硝基甲烷反应得到产物1-苯基-2-硝基乙醇,并探讨溶剂、催化剂用量和三乙胺等因素对催化反应的影响。结果表明:在三乙胺存在的条件下,以甲醇为溶剂、以10mol%的配合物为催化剂,该金属配合物具有良好的催化活性。

A novel copper metal complex using 3-（diethylamino）propylamine as ligand was synthesized and characterized by elemental analysis and IR spectroscopy.1-Phenyl-2-nitroethanol was attained by the reaction of benzaldehyde to nitromethane with the complex as catalyst,and the influences on the reaction,including solvent,catalyst loading and triethylamine have been discussed.The results showed that the complex exhibited high catalytic activity in the following conditions：the solvent was methanol,the catalyst loading was 10 mol%,and in the help of triethylamine.
