Abstract

An ultrasound-assisted, simple, fast and efficient method reported for the chemoselective N-formylation of amines with formic acid in the presence of nanozeolite clinoptilolite (nano-CP) under solvent-free reaction conditions to give the corresponding formamides. The ultrasound increased the rate of the reaction and afforded excellent yields at room temperature. This method has the advantages of high yields, mild conditions, simple methodology, easy work up and short reaction times. The catalyst was characterized by different techniques, was recovered and reused several times without the significant loss of its catalytic performance.

纳米斜发沸石作为绿色催化剂,用于胺的快速和化学选择性N-甲酰化

摘要

超声辅助,简单,快速,有效的方法报道了在无溶剂反应条件下,在纳米沸石斜发沸石(nano-CP)存在下,胺与甲酸进行化学选择性的N-甲酰化反应,从而得到相应的甲酰胺。超声提高了反应速率,并在室温下提供了优异的产率。该方法具有收率高,条件温和,方法简单,后处理容易,反应时间短的优点。该催化剂具有不同的技术特征,可以回收并重复使用几次,而不会显着降低其催化性能。
