The first catalytic application of well-defined (P,C) cyclometalated gold(III) complexes is reported. The bench-stable bis(trifluoroacetyl) complexes 2 a,b perform very well in the intermolecular hydroarylation of alkynes. The reaction is broad in scope, it proceeds within few hours at 25 °C at catalytic loadings of 0.1-5 mol %. The electron-rich arene adds across the C≡C bond with complete regio- and stereo-selectivity. The significance of well-defined gold(III) complexes and ligand design are highlighted in a powerful but challenging catalytic transformation.
报道了结构明确的（磷，碳）环金属化金（III）配合物的首次催化应用。稳定性良好的双（三氟乙酰基）配合物2 a,b在炔烃的分子间氢芳基化反应中表现出色。该反应适用范围广，在25 °C下，催化负载量为0.1 - 5 mol %时，反应在数小时内即可完成。富电子芳烃以完全的区域和立体选择性加成到C≡C键上。在一个强大但具有挑战性的催化转化中，突出了结构明确的金（III）配合物和配体设计的重要性。
