Abstract

original image

Arm, aber erfolgreich: BFPy-Phosphane (siehe Schema) imitieren den elektronischen und sterischen Charakter von P(C6F5)3 bzw. PPh3. Diese neuartigen Liganden zeigen eine stark beschleunigende Wirkung auf Stille-Kupplungen, die Rh-katalysierte 1,2-Addition von Arylboronsäuren an nichtaktivierte Ketone sowie die asymmetrische Arylierung von N-Tosylimin mithilfe von Phenylboronsäure.
