文摘

A new, efficient and green protocol for the nano-Cu₂O-catalyzed homo-coupling reaction of terminal alkynes has been developed, using water/ionic liquid as an environmentally friendly solvent. Moreover, the system also allows the synthesis of unsymmetric 1,3-diynes by cross-coupling of two different terminal alkynes. It is noteworthy that the nano-Cu₂O-catalyzed methodology is a good supplement to copper catalyst for the Glaser-type homo-coupling reaction. Copyright
