A new site-selective hydroarylation reaction of alkynes catalyzed by gold complexes and directed by an internal hydroxyl group has been developed. Thus, the treatment of 3-butyn-1-ol derivatives with indoles and a catalytic amount of an in situ formed cationic gold complex leads to the formation of bis(indolyl)alkane derivatives. Particularly interesting is the reaction with terminal alkynes as the
