A high efficient method for the synthesis of 1,3-diynes derivatives which employed terminal alkynes as the substrates and copper(I) oxide as the catalyst was developed. This method possessed the character of base-free and mild reaction conditions. The reaction mechanism was also studied. Furthermore, this reaction could be magnified to gram scale and the catalyst of copper(I) oxide could be recycled.

Key words: copper (I) oxide, homocoupling, terminal alkynes, base-free
