Palladium β-diiminate chemistry: Reactivity towards monodentate ligands and arylboronic acids
Inorganica Chimica Acta, 2012•Elsevier
Here we report the synthesis and characterization of a series of palladium β-diiminate
complexes. Chloro-bridged dimers [Pd (Ar2nacnac)(μ-Cl)] 2 (where [Ar2nacnac]− is [(ArNC
(CH3)) 2CH]− with Ar being aryl substituents) can serve as versatile starting materials, and
can be cleaved by neutral monodentate ligands (L) to form mononuclear complexes [Pd
(Ar2nacnac)(L) Cl], or engage in unusual transmetallation reactions with boronic acids to
form tetrapallada-macrocycles. The reactivity of the tetrapallada-macrocyclic complexes …

The reactivity of the tetrapallada-macrocyclic complexes towards L-type ligands, as well as the reactivity of Pd(Ar2nacnac)(L)Cl] complexes towards boronic acids was also explored.
