homogeneous catalysts. In contrast, very limited progress has been made with the use of cheap, Earth‐abundant base metals as heterogeneous catalysts for these transformations—in spite of the obvious economic and environmental advantages. Herein, we report on the use of an easily prepared heterogeneous catalyst material for the migration of olefins, in particular, for allylarenes. The catalyst material
烯丙基芳烃中的烯烃迁移通常使用贵金属基均相催化剂进行。相反,尽管有明显的经济和环境优势,但使用廉价的,富含地球的贱金属作为这些转化的非均相催化剂所取得的进展非常有限。本文中,我们报道了使用易于制备的非均相催化剂材料用于烯烃,特别是烯丙基芳烃的迁移。催化剂材料由包裹在氮掺杂碳壳中的镍/钴合金纳米颗粒组成。包封的纳米颗粒在空气中稳定,可以通过离心,过滤或磁力分离轻松收集。此外,我们证明了该催化剂可重复使用多次,并能连续提供高产率的烯烃迁移产物。
