Synthesis and Reactivity of Air-Stable N-Heterocyclic Carbene Gold(I) Bis(trifluoromethanesulfonyl)imidate Complexes

International audienceA study concerning the synthesis of new N-heterocyclic carbene gold(I) complexes using the bis(trifluoromethanesulfonyl)imidate moiety (Tf2N-) as a weakly coordinating counteranion is described. These new air-stable (NCH)AuNTf2 complexes are convenient to prepare, stoe, and handle and proved to be active in a range of gold(I)-catalyzed transformations
