able to use highly steric hindered phenols, small changes on the steric bulk of the alkynes have a dramatic effect on the reactivity. More importantly, we have observed that the use of substrates that facilitate the formation of diaurated species such as gem-diaurated or sigma,pi-digold-acetylide species, hinder the catalytic activity. Moreover, we have identified that the use of directing groups in
