Abstract:
We report the synthesis, characterization and reactivity of an air-stable, well-defined acenaphthoimidazolylidene palladium–BIAN–NHC chloro dimer complex, [Pd(BIAN–IPr)(μ-Cl)Cl] 2 . This rapidly activating catalyst merges the reactive properties of palladium chloro dimers, [Pd(NHC)(μ-Cl)Cl] 2 , with the attractive structural features of the BIAN framework. [Pd(BIAN–IPr)(μ-Cl)Cl] 2 is the most reactive Pd( ii )–NHC precatalyst discovered to date undergoing fast activation under both an inert atmosphere and aerobic conditions. The catalyst features bulky-yet-flexible sterics that render the C–H substituents closer to the metal center in combination with rapid dissociation to monomers and strong σ-donor properties. [Pd(BIAN–IPr)(μ-Cl)Cl] 2 should be considered as a catalyst for reactions using well-defined Pd( ii )–NHCs.
