Cover Picture: Ruthenium-Catalyzed Asymmetric Propargylic Substitution Reactions of Propargylic Alcohols with Acetone (Angew. Chem. Int. Ed. 47/2005)

44_47/2005Diruthenium complexes with optically active thiolate-bridged ligands promote the catalytic propargylic substitution of propargylic alcohols with acetone as the nucleophile. The use of novel chiral ligands bearing a phenyl ring that can engage in a π–π interaction with a phenyl ring of the ruthenium–allenylidene moiety lead to high enantioselectivities in these processes. For more details, see the Communication by Y. Nishibayashi and co-workers on page 7715 ff.
