A facile and efficient pathway for the copper iodide and ligand N,N,N′,N′‐tetramethylethane‐1,2‐diamine promoted homocoupling reaction of terminal alkynes under ambient temperature and air as an oxidant was reported. The alkynes, including aromatic alkynes and aliphatic alkynes, could afford the symmetrical 1,4‐disubstituted 1,3‐diynes in good to excellent yields.
据报道,在环境温度和空气作为氧化剂的条件下,碘化铜和配体N,N,N',N'-四甲基乙烷-1,2-二胺促进了末端炔烃的均偶联反应的简便有效途径。炔烃,包括芳族炔烃和脂族炔烃,可以提供对称的1,4-二取代的1,3-二炔,收率高至优异。
