The synthesis and characterization of a series of N-heterocyclic carbene (NHC) complexes of Au(iii), (NHC)AuCl, is described. High yields are obtained when the corresponding Au(i) species (NHC)AuCl are oxidized with inexpensive aqua regia. The oxidation is in some cases accompanied by substitution and/or anti addition of Cl across the backbone C[double bond, length as m-dash]C bond of unsaturated NHC ligands.
描述了一系列金(III)的N-杂环卡宾(NHC)配合物(NHC)AuCl的合成与表征。当相应的金(I)物种(NHC)AuCl用廉价的王水氧化时可获得高产率。在某些情况下,氧化伴随着氯在不饱和NHC配体的主链C═C键上的取代和/或反式加成。
