Abstract

The bis(diphenylphisphino)ferrocene (dppf) derived palladium analogue of [PdCl₂(dppf)] on reaction with the sodium salt of pyridyl/pyrimidyl selenolate yielded mononuclear cis configured complex [Pd(SeAr)₂(dppf)] (Ar = C₅H₄N, C₄H(4,6-Me)₂N₂), as did the platinum precursor [PtCl2(dppf)] with methyl substituted pyrimidyl salt giving [Pt{SeC₄H(4,6-Me)₂N₂}2(dppf)]. In contrast, the reaction of platinum precursor with the sodium salt of pyridylselenolate gave two different complexes [Pt₂(μ-SeC₅H₄N)₂(dppf)₂]²⁺ and [Pt(Cl)(SeC₅H₄N)(dppf)] depending in the reaction solvent. These complexes were characterized by elemental analysis and NMR (¹H, ³¹P) spectroscopy. The molecular structure of [Pt{SeC₄H(4,6-Me)₂N₂}2(dppf)] was established by single crystal X-ray diffraction analysis.
