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 1 H and 13 C 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 cyclization processes employing a variety of alkynes as starting materials. According to the overall results, the trinuclear complex 3 displayed the highest catalytic activity in all processes, providing good to excellent yields under mild reaction conditions.
