14 new gold(I) NHC complexes of the type [AuX(Pr-bimy)] (Pr-bimy = 1,3-diisopropylbenzimidazolin-2-ylidene) have been prepared and fully characterized. These complexes and their reported analogues were used to systematically compare and rank the donating abilities of overall 34 anionic X-type donors by C NMR spectroscopy. Specifically, the carbene chemical shift of the Pr-bimy ligand was found to be responsive to the ligand X spanning an overall range Δδ > 37 ppm between the strongest and weakest donor in this study.
已制备并全面表征了14种新型[AuX(Pr-bimy)]类型的金(I) NHC配合物（Pr-bimy = 1,3 - 二异丙基苯并咪唑 - 2 - 亚基）。通过碳核磁共振光谱法，利用这些配合物及其已报道的类似物，对总共34种阴离子X型供体的给电子能力进行了系统比较和排序。具体而言，在本研究中，发现Pr-bimy配体的卡宾化学位移对配体X有响应，最强供体和最弱供体之间的总范围Δδ > 37 ppm。
