Cyclometallated compounds, particularly with palladium and platinum, have been extensively studied over the past years in part due to their applications as catalysts in cross-coupling reactions. They are also useful in medicinal chemistry, and quite a large number have luminescent properties.
Herein, the synthesis and characterization of novel palladium cyclometallated compounds and a study of their reactivity with a diphosphine ligand is discussed. Mono- and dinuclear compounds were prepared depending on phosphine ligand coordination.
Characterization has been carried by IR spectroscopy, 1H and 31P NMR spectroscopy.
