Copper‐Catalyzed Arylation of Nucleophiles by Using Butadienylphosphines as Ligands: Mechanistic Insight

Abstract

Dien mit Vorzügen: Das Butadienylphosphan L (siehe Schema) ist in großen Mengen durch eine neue Synthesemethode zugänglich. Kupferkatalysierte Ullmann-Arylierungen mit diesem effizienten Liganden konnten 31P-NMR-spektroskopisch verfolgt werden, um einen Reaktionsmechanismus zu postulieren.
