Abstract In this study, Fe 3 O 4 @LDH@cysteine–Cu(I) nanoparticles as a novel and recyclable catalytic system was designed and successfully synthesized. These nanoparticles show high catalytic activity for preparation of the triazole family through reaction of the organic halides with alkynes in the presence of choline azide as reagent and reaction medium. In addition, Fe 3 O 4 @LDH@cysteine–Cu(I)
摘要 在本研究中,设计并成功合成了 Fe 3 O 4 @LDH@半胱氨酸-Cu(I) 纳米粒子作为一种新型可回收的催化体系。这些纳米颗粒在叠氮化胆碱作为试剂和反应介质的情况下,通过有机卤化物与炔烃的反应,对制备三唑族显示出高催化活性。此外,Fe 3 O 4 @LDH@cysteine-Cu(I) 可以很容易地回收和重复使用五次,催化活性没有任何显着损失。图形摘要
