摘要：

The resting state of the gold(I)-catalyzed hydroarylation of 1 changes In the presence of Ag+, with silver free catalysts resting at the dinuclear gold structure 5 and Ag+ containing solutions resting at a heteronuclear species like 6. Adventitious Ag+ (typically from LAuCl activation) can therefore intercept key organogold intermediates and effect the catalysis even when it does not effect the reaction in Au free control experiments.
