Reactivity of Gold Hydrides: O(2) Insertion into the Au–H Bond

[Image: see text] Dioxygen reacts with the gold(I) hydride (IPr)AuH under insertion to give the hydroperoxide (IPr)AuOOH, a long-postulated reaction in gold catalysis and the first demonstration of O(2) activation by Au–H in a well-defined system. Subsequent condensation gave the peroxide (IPr)Au–OO...

Sumario:[Image: see text] Dioxygen reacts with the gold(I) hydride (IPr)AuH under insertion to give the hydroperoxide (IPr)AuOOH, a long-postulated reaction in gold catalysis and the first demonstration of O(2) activation by Au–H in a well-defined system. Subsequent condensation gave the peroxide (IPr)Au–OO–Au(IPr) (IPr = 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene). The reaction kinetics are reported, as well as the reactivity of Au(I) hydrides with radical scavengers.
