A novel synthetic approach for the synthesis of gold(iii) acetato, alkoxolato and alkynyl complexes was developed via the reactivity of gold(iii) trications containing the N,N-chelating ligand 2,2'-bipyridine and N,N,N-chelating ligand terpyridine through direct reactions with the protic precursors. This protocol avoids the gold(iii) chloride bond activation pathway commonly employed to access these functionalities. For example exposure of [LAu(iii)L']OTf (L = N,N,N-terpyridine, L' = 4-DMAP) to RH (R = OCH, OAc, Ph-[triple bond, length as m-dash]) results in the facile formation of the corresponding functionalised gold(iii) complexes [LAu(iii)R]OTf.
通过含有N，N-螯合配体2,2'-联吡啶和N，N，N-螯合配体三联吡啶的金（III）三阳离子与质子前体的直接反应，开发了一种合成乙酸金（III）、烷氧基金（III）和炔基金（III）配合物的新型合成方法。该方案避免了通常用于获得这些官能团的氯化金（III）键活化途径。例如，将[LAu（III）L']OTf（L = N，N，N-三联吡啶，L' = 4-DMAP）暴露于RH（R = OCH、OAc、Ph-[三键，长度为m破折号]）会导致相应的官能化金（III）配合物[LAu（III）R]OTf的轻松形成。
