The stable Pt(II) complex [Pt(SPh)2(dppen) (4), (dppen, Ph2PCH=CHPPh2) was obtained from [PtCl(SPh)2(SnPh3)cod] (1) (cod = 1,5-cyclooctadiene) by reductive elimination reaction of SnClPh3 and substitution of the cod ligand by the diphosphine, albeit in low yields. Yields of 80% were obtained when [Pt(SPh)2cod] (3) was used as the starting material instead. The viability of these reactions was suggested by a TG study, performed on the starting materials. Complex 4 was characterized by multinuclear NMR (195Pt, 31P, 1H and 13C) and IR spectroscopies and elemental analysis. The molecular structure, solved by an X-ray diffraction study, exhibted a slightly distorted square-planar geometry and short C=C and Pt-P bond distances which were interpreted in terms of a p interaction between the double bond and the metal-ligand bond, as observed for other diphosphine compounds described previously.
