A series of mono‐ to trinuclear gold(I) complexes (1–3) supported by oxo‐functionalized 1,2,3‐triazolylidenes have been prepared. All new compounds were fully characterized by means of 1H and 13C NMR spectroscopy, elemental analyses, and in the case of complexes 1 and 2 by x‐ray diffraction. The catalytic performance of the new triazolylidene gold complexes was tested in several hydroelementation and
制备了一系列由羰基官能化的1,2,3-三唑基亚甲基支持的单核至三核金(I)配合物(1-3)。所有新化合物均已通过1 H和13 C NMR光谱,元素分析以及对于复合物1和2的X射线衍射进行了充分表征。在使用多种炔烃作为起始原料的几种加氢元素化和环化过程中,测试了新的三唑基亚金络合物的催化性能。根据总体结果,三核配合物3在所有过程中均显示出最高的催化活性,在温和的反应条件下提供了良好或优异的收率。
