Decarboxylation reactions between the complexes cis –[PtCl 2 L] (L = 1, n–bis(diphenylphosphino)–ethane (n = 2, dppe), –propane (n = 3, dppp) or –butane (n = 4, dppb)) and thallium(I) pentafluorobenzoate in pyridine give cis –[PtCl(C 6 F 5 )L] and cis –[Pt(C 6 F 5 ) 2 L] complexes in high yields with short reaction times. X–ray crystal structures of cis –[PtCl(C 6 F 5 )(dppe)] · 0.5 C 5 H 5 N, cis –[PtCl(C 6 F 5 )(dppp)], cis –[PtCl(C 6 F 5 )(dppb)] · C 3 H 6 O, cis –[Pt(C 6 F 5 ) 2 L] (L = dppe, dppp and dppb) and the reactants cis –[PtCl 2 (dppp)] (as a CH 2 Cl 2 solvate) and cis –[PtCl 2 (dppb)] show monomeric structures with chelating diphosphine ligands in all cases rather than dimers with bridging diphosphines. 31 P NMR data are consistent with these structures in solution.
