Resumen: Gold catalysis has witnessed immense evolution in recent years, yet it still requires the use of activators to render the common [AuCl(L)] complexes catalytically active. Despite the remarkable achievements using the additive, ligand and catalyst design approach for catalyst activation, a simple solution to this problem is still lacking. Indeed, it would be ideal to uncover conditions under which several gold catalyzed reactions could operate under a [AuCl(L)] catalysis regime. This would enable the utilization of the most common, stable, and least expensive complexes in gold catalysis, simplifying the catalyst generation step involved in a plethora of transformations. Different modes of activation of the most common, stable, and less expensive commercial gold catalysts will be discussed.
