in good yields and high purity from the corresponding maleamic acids using a Brønsted acidic room temperature ionic liquid (RTIL) as a catalyst. The products were obtained through merely a decanting and removal of the solvent, suggesting that this procedure is superior to the conventional routes, in which the strong organic/inorganic acids were used as the catalysts, as well as a complicated post-processing
使用布朗斯台德酸性室温离子液体(RTIL)作为催化剂,从相应的马来酰胺酸中以高收率和高纯度合成了七个马来酰亚胺衍生物。仅通过de析和除去溶剂即可获得产物,这表明该方法优于常规方法,在常规方法中,使用强有机/无机酸作为催化剂,并且对烃类进行了复杂的后处理程序。使用产物的分离和纯化。
