ResumoPraktische Zwischenstufen, die bei der Gold(I)-katalysierten intramolekularen 1,(n−1)-Wanderung von 1,n-Eninen mit Propargylalkohol-, Propargylether- oder Propargylsilylether-Einheiten über Allylgoldkationen entstehen, lassen sich mit Olefinen, mit Indol und durch eine formale intramolekulare C-H-Insertion abfangen. Bei arylsubstituierten 1,7-Eninen liefert eine Kaskade unter Beteiligung einer Nazarov-Cyclisierung 6,7-Dihydro-5H-benzo[c]fluorene.
