of unsymmetric diaryl gold N-acyclic carbene (NAC) complexes was synthesized via the isonitrile route by three different methods: (a) solvent free in a melt, (b) mechanochemically and (c) in THF at room temperature. The latter method can also be used to synthesize unsaturated gold NHC complexes. These methods overall offer access to a broad array of new complexes and remove one of the previous limitations
各种不对称二芳基金 N-无环卡宾( NAC) 配合物通过异腈路线通过三种不同的方法合成:(a) 熔体中无溶剂,(b) 机械化学和 (c) 在室温下在 THF 中。后一种方法也可用于合成不饱和金 NHC 配合物。这些方法总体上提供了获得广泛的新配合物的途径,并消除了以前异腈路线对 NAC 和 NHC 金配合物的限制之一,即不能与亲核性较低的芳香胺反应。新的配合物也被证明在金催化苯酚合成中作为预催化剂是成功的。
