Meldrum's acid catalyzed the reaction of tetracyanoethylene with aromatic, heteroaromatic, and conjugated aldehydes led to arylidenemalononitrile in water in good yields at 80 °C. The work-up of reactions is very simple and the crude products are sufficiently pure to be used without further purification. The procedure provides an alternative method for the synthesis of arylidenemalononitrile.
在 Meldrum 酸催化下,四氰基乙烯与芳香族、杂芳香族和共轭醛发生反应,在 80 °C 温度下在水中生成芳基亚甲基丙二腈,收率良好。反应的操作非常简单,粗产物的纯度很高,无需进一步纯化即可使用。该步骤为合成芳基亚甲基丙二腈提供了另一种方法。
