Water-Stabilized Three- and Four-Atom Palladium Clusters as Highly Active Catalytic Species in Ligand-Free CC Cross-Coupling Reactions

Elite cliques: Palladium clusters with three and four atoms were found to be the catalytically active species for ligand‐free palladium‐catalyzed CC bond‐forming reactions (see picture).

Zusammenfassung:Elite cliques: Palladium clusters with three and four atoms were found to be the catalytically active species for ligand‐free palladium‐catalyzed CC bond‐forming reactions (see picture). These palladium cluster species could be stabilized in water and stored for long periods of time for use on demand with no loss of activity. High yields of products and turnover frequencies (TOFs) of up to 105 h−1 were observed.
