In the reaction of (3,5-dimethyl-1H-pyrazol-1-yl)methyldiphenylphosphinite (dmpmp) with [PdCl2(CH3CN)2], we have obtained hydrolysis and phosphorus oxidation products and the unexpected complex cis-[PdCl2(dmbpm)] (dmbpm=bis(3,5-dimethyl-1H-pyrazol-1-yl)methane). Modifications in the synthesis of dmpmp (high temperature, strong base, and the presence of Ph2P(O)Cl) show that dmbpm is a by-product from the synthetic route to dmpmp. The complex cis-[PdCl2(dmbpm)] is isolated and fully characterized by mass spectrometry, analytical, and spectroscopy techniques and the crystal structure is obtained by X-ray diffraction methods. © 2009 Taylor & Francis.
