A convenient and efficient chiral CuFe2O4@SiO2-Mn(III) Ch.salen nanocatalyst has been developed for the C-N cross-coupling reactions of aryl halides/ phenylboronic acid with N-heterocyclic compounds in water and/or DMSO under mild conditions. The catalyst could be applied for the N-arylation of a variety of nitrogen-containing heterocycles with aryl chlorides, bromides, iodides and phenylboronic acid under mild conditions. Moderate to good yields were achieved for all substrates. The structure of catalyst was characterized using various techniques including FT-IR, FE-SEM, EDX, XRD, TEM and TGA. The catalyst can be simply recovered and reused for several times without significant loss of activity.

已经开发了一种方便有效的手性CuFe2O4 @ SiO2-Mn（III）Ch.salen纳米催化剂，用于在温和条件下在水中和/或DMSO中将芳基卤化物/苯基硼酸与N-杂环化合物进行CN交叉偶联反应。该催化剂可用于在温和条件下将各种含氮杂环与芳基氯化物，溴化物，碘化物和苯基硼酸进行N-芳基化反应。所有底物均达到中等至良好的产率。催化剂的结构采用多种技术进行表征，包括FT-IR，FE-SEM，EDX，XRD，TEM和TGA。催化剂可以简单地回收并重复使用几次，而不会显着降低活性。
