Synthesis and X-ray structure of neutral Pd(IV) hydride complexes supported by β-ketoimine ligands

A series of neutral palladium(IV) hydride complexes supported by β-ketoimine ligands was synthesized. Reaction of dichlorobis(acetonitrile)palladium(II) with β-ketoamines (1–4) in dichloromethane at room temperature generated dark red solids of [PdCl2(β-ketoimine)(H)] (6–9) in which the central carbon of the ketoimine ligand is σ-bound to the palladium. All the new complexes have been characterized by NMR and IR spectroscopy. The structure of complex(9) has been solved by X-ray crystallography.

New neutral hydride complexes of palladium(IV) supported by β-ketoimine ligands have been synthesized and characterized. The X-ray structure determination of the complex (9) reveals that it adopts a distorted square planar arrangement. The central carbon atom of the β-ketoimine ligand is σ-bound to a PdCl2 fragment.Figure optionsDownload as PowerPoint slide
