文摘

The synthesis and characterization of anionic, neutral, and cationic hydride complexes of platinum and palladium are reported utilizing the PNP (PNP = 2,6-bis(di-tert-butylphosphinomethyl)pyridine) ligand. Comparisons by IR spectroscopy and X-ray crystallography are made across the series. Evaluation of the metal hydride stretching frequencies of the cationic through anionic complexes shows a trend of increasing M鈥揌 bond activation. The reactivity of these metal hydrides with oxygen is evaluated and compared to previously reported oxygen insertion reactions.
