Catch the gold fish: A number of enol ether derived diaurated species were synthesized directly from different alkynols and cationic gold complexes in the presence of a non-nucleophilic base (proton sponge; see scheme). The reaction can be easily applied for the in situ generation of diaurated species from all common types of hydroalkoxylation substrates: 5-endo, 5-exo/6-endo, 6-exo/7-endo and even intermolecular types. The reactivity of various gold oxo compounds (LAu)2OH+, (LAu)3O+, and LAuOH (L=phosphine ligand) towards alkynols was also examined.
