( Aksaray, Yazar )We report the reactivity of isolable Au(i)-hydride stabilized by an NHC-coordinated diphosphene towards substrates containing C-C and N-N multiple bonds (NHC = N-heterocyclcic carbene). Reactions with dimethyl acetylenedicarboxylate and azobenzene lead to a trans-addition of the Au(i)-H across the C-C triple bond and the N-N double bond, respectively. In contrast, the reaction with ethyl diazoacetate affords a gold(i)-hydrazonide as the 1,1-addition product to the terminal nitrogen atom. With phenyl acetylene, the corresponding Au(i)-alkynyl complex is obtained under the elimination of dihydrogen. Strikingly, diphosphene-containing Au(i)-hydride is more reactive-affording different products in some cases-than a related NHC-stabilized Au(i)-hydride without the mediating diphosphene moiety.eninfo:eu-repo/semantics/closedAccessReactivity of NHC/diphosphene-coordinated Au(i)-hydrideArticle57680981210.1039/d0cc05461e33367425Q1WOS:000611726300025Q2
