Silver‐Triggered Activity of a Heterogeneous Palladium Catalyst in Oxidative Carbonylation Reactions

A silver‐triggered heterogeneous Pd‐catalyzed oxidative carbonylation has been developed. This heterogeneous process exhibits high efficiency and good recyclability, and was utilized for the one‐pot construction of polycyclic compounds with multiple chiral centers. AgOTf was used to remove chloride...

Description
Summary:A silver‐triggered heterogeneous Pd‐catalyzed oxidative carbonylation has been developed. This heterogeneous process exhibits high efficiency and good recyclability, and was utilized for the one‐pot construction of polycyclic compounds with multiple chiral centers. AgOTf was used to remove chloride ions in the heterogeneous catalyst Pd‐AmP‐CNC, thereby generating highly active PdII, which results in high efficiency of the heterogeneous catalytic system. Silberpfeil: Eine durch Silber ausgelöste, heterogene, Pd‐katalysierte oxidative Carbonylierung von Allenamiden ermöglicht den Aufbau von Pyrrolidonen und polycyclischen Verbindungen mit mehreren Stereozentren. Der Katalysator (Pd‐AmP‐CNC) kann mindestens 9‐mal ohne Aktivitätsverlust verwendet werden. Das Ag‐Salz entfernt Cl von Pd‐AmP‐CNC und erzeugt dabei hoch aktives PdII, was zu der hohen Effizienz führt.
