The method of microwave-assisted synthesis of benzylidenemalononitrile and its derivatives by using N,N-dimethylformamide as the catalyst is found to be a superior alternative to the conventional method of synthesis. While the conventional methods in recent times have taken from several hours to a few minutes and produce an average yield, herein is reported the realization of a very similar reaction in comparatively much shorter time of a few seconds, producing a high yield. The products are characterized using infrared and nuclear magnetic resonance spectroscopy.

使用N，N-二甲基甲酰胺作为催化剂在Knoevenagel缩合反应中提高反应速率

发现使用N，N-二甲基甲酰胺作为催化剂的微波辅助合成苄叉基丙二腈及其衍生物的方法是常规合成方法的替代方法。尽管近来的常规方法已经花费了数小时到几分钟的时间并且产生了平均收率，但是本文报道了在相对短得多的几秒时间内实现非常相似的反应，从而产生了高收率。使用红外和核磁共振波谱对产品进行表征。
