of non‐toxic and magnetically separable nano‐CuFe2O4 as an efficient catalyst for oxidative homo‐ and cross‐coupling reaction of terminal alkynes is described. A wide range of symmetrical and unsymmetrical 1,3‐diynes have been synthesized in moderate to good yields under ambient atmosphere. The nano CuFe2O4 can be recovered with a magnet and reused at least five consecutive cycles with no appreciable

炔烃氧化均相和交叉偶联反应的有效催化剂的应用。在环境大气下,合成了多种对称和不对称的1,3-二炔,收率中等至良好。纳米CuFe 2 O 4可以用磁
铁回收,并至少连续五个循环重复使用,而其催化活性没有明显损失。
