离子液体催化合成2,2-二苄基取代丙二腈类化合物

Synthesis of 2,2-substituted benzyl malononitrile compound catalyzed by ionic liquids

采用苄基吡啶类离子液体催化合成了5种2,2-二苄基取代丙二腈类化合物,并通过红外光谱、氢核磁共振谱及单晶衍射进行表征,确定分子结构。制备过程条件较温和,后处理简单,离子液体回收再利用率高,为制备二苄基取代丙二腈类化合物提供了一种新的方法。

Five kinds of benzyl 2,2-substituted benzyl malononitrile compounds were synthesized with the catalyst of ionic liquids.The molecular structure was determined by IR,1 H NMR and X-ray analysis. The conditions of synthesis were mild and the work-upwas simple. The ionic liquids catalyst had a high recycling efficiency. The paper afforded a new method to synthesize 2,2-dibenzylsubstituted malononitrile.
