- The synthesis by decarboxylation reactions and crystal structures of 1,n-bis(diphenylphosphino)alkane(pentafluorophenyl)-platinum(II) complexes
-
Decarboxylation reactions between the complexes cis-[PtCl2L] (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(C6F5)L] and cis-[Pt(C6F 5)2L] complexes in high yields with short reaction times. X-ray crystal structures of cis-[PtCl(C6F5)(dppe)] ·0.5 C5H5N, cis-[PtCl(C6F 5)(dppp)], cis-[PtCl(C6F5)(dppb)]·C 3H6O. cis-[Pt(C6F5)2L] (L = dppe, dppp and dppb) and the reactants cis-[PtCl2(dppp)] (as a CH2Cl2 solvate) and cis-[PtCl2(dppb)] show monomeric structures with chelating diphosphine ligands in all cases rather than dimers with bridging diphosphines. 31P NMR data are consistent with these structures in solution.
