The reaction of N,N'-bis(2,6-diisopropylphenyl)imidazol-2-ylidene gold hydroxide ([Au(OH)(IPr)]; 1) with acetylene and trimethylsilylacetylene derivatives cleanly leads to the formation of a gold-acetylide bond with the concomitant formation of water or trimethylsilanol. All compounds were isolated in high yield (>85%). The crystal structures of selected gold acetylides in conjunction with their UV-vis absorption/emission properties were investigated. Finally, DFT calculations were performed in an attempt to gain an insight into the mechanism of the general reaction.
N,N'-双(2,6-二异丙基苯基)咪唑-2-亚基金氢氧化物([Au(OH)(IPr)]; 1)与乙炔和三甲基硅基乙炔衍生物反应，可干净地形成金-炔键，同时形成水或三甲硅醇。所有化合物均以高产率(>85%)分离。研究了所选金炔化物的晶体结构及其紫外可见吸收/发射特性。最后，进行了 DFT 计算，试图深入了解一般反应的机理。
