Spot the difference! Different intramolecularrearrangements of vinylidenecyclopropanes containing a secondary alcohol chain were observed depending on whether the reaction was catalyzed by a gold(I) complex or a Brønsted acid (HOTf; OTf=trifluoromethanesulfonate). The corresponding adducts were obtained in moderate to good yields (see scheme). The scope and limitations of these reactions, as well
