gold-aryl compounds bearing N-heterocyclic carbene (NHC) ligands sparked an investigation of their reactivity and potential utility as organometallic synthons. The use of a mild base and green solvents provide access to these compounds, starting from widely available boronic acids and various [Au(NHC)Cl] complexes, with reactions taking place under air, at room temperature and leading to high yields with unprecedented
可持续且可扩展的合成规程的发现导致带有N杂环卡宾(NHC)配体的金芳基化合物的发现引发了对其作为有机金属合成子的反应性和潜在用途的研究。使用温和的碱和绿色溶剂可从广泛使用的硼酸和各种[Au(NHC)Cl]络合物开始,在空气中,室温下进行反应,从而获得高收率,并且前所未有的轻松。一种化合物,(N,N'-双[2,6-(二异丙基)苯基]咪唑-2-亚烷基)(4-甲氧基苯基)金,([Au(IPr)(4-MeOC6 H4)]),以克为单位合成,并用于评估这类化合物对CH / NH键以及与各种酸的反应性,
