    Resum:
    Gold(I) acetylide and sigma,pi-digold(I) alkyne complexes derived from one prototypical 1,6-enyne and from 7-ethynyl-1,3,5-cycloheptatriene have been prepared and structurally characterized. Their possible role in gold(I)-catalyzed cycloisomerizations has been studied by experiment and by DFT calculations. Gold(I) acetylides are totally unproductive complexes in the absence of Bronsted acids. Similarly, no cyclizations were observed by heating sigma,pi-digold(I) alkyne digold(I) at least up to 130 degrees C. Theoretical studies provide a rationale for the much lower reactivity of digold species in reactions of enynes.
