摘要/Abstract
报道了锌-脯氨酸复合物催化下的水相Knoevenagel缩合反应.17种芳香醛以及2种脂肪环酮与丙二腈在80℃下反应5～10 min，能够以84%～99%的收率得到相应的Knoevenagel缩合产物.催化剂回收重复使用10次，其催化活性不受影响.
关键词: Knoevenagel缩合, 水相反应, 锌-脯氨酸复合物, 环境友好
Zinc-proline complex catalyzed Knoevenagel condensation in water was reported. Seventeen aldehydes and two ketones were investigated, which coupled with malononitrile smoothly affording desired Knoevenagel condensation products in 5~10 min at 80℃ in the yields of 84%~99%. The catalyst can be recovered and reused for ten cycles without loss of activity.
Key words: Knoevenagel condensation, aqueous media, zinc-proline complex, environmentally benign
