Cover Picture: Cationic Gold(i) Complexes: Highly Alkynophilic Catalysts for the exo- and endo-Cyclization of Enynes (Angew. Chem. Int. Ed. 18/2004)

43_18/2004Lauding the rings in the realm of metal-catalyzed cyclizations, where many mechanistic shadows lie: Gold is master, particularly in reactions that proceed through metal cyclopropylcarbene intermediates. In their Communication on page 2402 ff., A. M. Echavarren and co-workers report on their quest to discover cationic gold(i) complexes that selectively promote skeletal rearrangements and other enyne cyclizations under mild conditions.
