AbstractA green, efficient, and rapid procedure for the synthesis of N,N′-arylidene bisamide derivatives has been developed by one-pot condensation of aldehydes and amides in the presence of tris(hydrogensulfato)boron as a highly effective heterogeneous catalyst under solvent-free conditions at 100 °C. Various aromatic aldehydes, acetamide or benzamide were used in the reaction, and in all cases the
摘要在三(氢硫酸根)硼作为高效多相催化剂存在下,通过一锅缩合醛和酰胺,开发了一种绿色,高效,快速的合成N,N'-亚芳基双酰胺衍生物的方法。 100°C下的自由条件。反应中使用了各种芳香醛,乙酰胺或苯甲酰胺,在所有情况下均成功合成了所需的产物。该方法具有收率高,反应干净,环境友好,操作简便,方法简单,反应时间短的优点。 图形概要 。
