C–N cross-coupling reaction catalysed by reusable CuCr<sub>2</sub>O<sub>4</sub> nanoparticles under ligand-free conditions: a highly efficient synthesis of triarylamines
A convenient, efficient and ligand-free method for the C–N coupling reaction of anilines and aryliodides was performed using CuCr2O4 nanoparticles. Copper chromite nanocatalyst improved the rate and facility of the synthesis of triarylamines. The heterogeneous catalyst was fully characterized by scanning electron microscopy, IR and X-ray diffraction techniques. Recyclability, excellent yields of products
使用CuCr 2 O 4纳米粒子进行了一种方便,有效且无配体的苯胺与碘代芳烃C-N偶联反应的方法。亚铬酸铜纳米催化剂提高了三芳基胺合成的速率和设备。通过扫描电子显微镜,IR和X射线衍射技术充分表征了非均相催化剂。通过使用CuCr 2 O 4纳米粒子,可回收性,优异的产品收率和较短的反应时间是这种无配体方法的重要优势。
