以N-杂环卡宾（NHC）氢氧化金（I）[Au（OH）（IPr）]（IPr = N，N '-双（2，6-二异丙基苯基）咪唑-2-亚基）为前体，通过质子反应合成了一系列阳离子杂配体[Au（NHC）（NHC'）]（+）和[Au（NHC）（PR_3）]（+）配合物.用适当的酸式盐裂解。通过H-1和C-13 NMR光谱和单晶X-射线衍射进行了完整的表征，以辨别阳离子混配[Au（NHC）（NHC '）]（+）和[Au（NHC）（PR 3）]（+）同系物之间的电子和结构差异。
The use of the versatile N-heterocyclic carbene (NHC) gold(I) hydroxide [Au(OH)(IPr)] (IPr = N,N '-bis(2,6-diisopropylpheny)imidazol-2-ylidene) as precursor permits the expedient synthesis of a series of cationic heteroleptic [Au(NHC)(NHC')](+) and [Au(NHC)(PR3)](+) complexes by proton. lysis with the appropriate acid salts. Complete characterization by H-1 and C-13 NMR spectroscopy and by single-crystal X-ray diffraction was performed in order to discern electronic and structural differences between cationic heteroleptic [Au(NHC)(NHC')](+) and [Au(NHC)(PR3)](+) congeners.
