The synthesis and characterization of a series of new cationic gold(I) complexes with hydroxyl-functionalized N-heterocyclic carbene (NHC) ligands is described. They are valuable building blocks for further derivatization: as a first example, coupling with amino acids and a dipeptide, respectively, successfully results in amino acid and peptide conjugates that are hard to obtain by other synthetic routes.

羟基官能化的N-杂环卡宾金（i）配合物和肽结合物的合成†

描述了具有羟基官能化的N-杂环卡宾（NHC）配体的一系列新型阳离子金（I）配合物的合成和表征。它们是进一步衍生化的有价值的组成部分：作为第一个例子，分别与氨基酸和二肽偶联，可成功产生难以通过其他合成途径获得的氨基酸和肽结合物。
