Palladium β-diiminate chemistry: Reactivity towards monodentate ligands and arylboronic acids

► Synthesis and characterization of a series of Pd(II) β-diiminate complexes. ► Cleavage of Pd(II) β-diiminate chloro-bridged dimers by neutral monodentate ligands. ► Unusual transmetallation reactions to form tetrapallada-macrocycles. ► Reactivity of tetrapallada-macrocycles with monodentate ligands. ► Ligand abstraction from Pd(II) β-diiminate complexes by boronic acids.
