The homocoupling reaction of alkynes was carried out in the presence of 10 mol% AuCl3 using I2 as oxidant to generate 1,3-diynes products in high yield. The method is simple, safe and efficient. Both aryl and alkyl substituted alkynyl substrates reacted smoothly. AuClPPh3 also showed comparable catalytic activity to this transformation under a nitrogen atmosphere.
