Au-Catalyzed Homocoupling of Terminal Alkynes

Abstract:

The homocoupling reaction of alkynes was carried out smoothly in the presence of 10 mol% AuCl3 using I2 as oxidant to generate diyned products in high yields. The method is simple, efficient, safe and AuClPh3 also showed comparable catalytic activity to this transformation.
