Dinuclear gold(I)‐N‐heterocyclic carbenecomplexes were developed for the hydrohydrazidation of terminal alkynes. The gold(I)‐N‐heterocyclic carbenecomplexes 2a‐2b were synthesized in good yields from silver complexes synthesized in situ, which in turn were obtained from the corresponding imidazolium salts with Ag2O in dichloromethane as a solvent. The new air‐stable gold(I)‐NHCcomplexes, 2a‐2b, were
