Abstract
An Fe(3)O(4) nanoparticle-supported copper(I) pybox catalyst, which exhibits excellent reactivity and yields products with good enantioselectivity, was developed. As a proof of concept, six optically active propargyl amines were obtained in excellent yields. The catalyst can be magnetically removed and recycled easily six times without a decrease in activity or enantioselectivity.
摘要
开发了一种负载 Fe(3)O(4)纳米粒子的铜（I）pybox 催化剂，该催化剂具有出色的反应活性和产物的良好对映选择性。作为概念验证，六手性丙炔胺以优异的产率得到。该催化剂可以通过磁性轻易地分离和回收六次，活性和对映选择性没有降低。
