Copper oxide nanoparticles have been applied as an efficient catalyst for the formation of C–N bonds. They can catalyze diaminations for the regiospecific synthesis of 1,2‐disubstituted benzimidazoles from 1,2‐dihaloarenes and N‐arylamidines. The best performance has been achieved using CuO nanoparticles with average diameter of 6.5 nm. In addition, the catalyst can be recycled and reused without any
氧化铜纳米粒子已被用作形成C–N键的有效催化剂。它们可以催化从1,2-二卤代芳烃和N-芳基idine胺合成1,2-二取代的苯并咪唑的区域特异性的氨化反应。使用平均直径为6.5 nm的CuO纳米颗粒已获得最佳性能。另外,催化剂可以循环使用,而催化活性没有明显降低。版权所有©2016 John Wiley&Sons,Ltd.
