Dinuclear gold-silver resting states may explain silver effects in gold(I)-catalysis.

ABSTRACT: 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.
