Phosphine Functionalized Cp<sup>C</sup> Ligands and Their Metal Complexes

Simple nucleophilic aliphatic substitution gives access to mono- and diphosphine ligands with a Cp<sup>C</sup> group in the backbone. The monophosphine ligand coordinates to gold(I) via the phosphine site, to thallium(I) via the cyclopentadienyl site and to ruthenium(II) via a combinatio...

description Simple nucleophilic aliphatic substitution gives access to mono- and diphosphine ligands with a Cp<sup>C</sup> group in the backbone. The monophosphine ligand coordinates to gold(I) via the phosphine site, to thallium(I) via the cyclopentadienyl site and to ruthenium(II) via a combination of both, resulting in an <i>ansa</i>-type structure. Coordination with the cyclopentadiene site is not possible for the diphosphine ligand. In this case, monodentate coordination to gold(I) and bidentate coordination to the [PdCl(μ<sup>2</sup>-Cl)]<sub>2</sub>, the [Rh(CO)(μ<sup>2</sup>-Cl)]<sub>2</sub>, and the Rh(CO)Cl fragment is observed, showing the variability in coordination modes possible for the long-chain diphosphine ligand. Ligands and complexes were characterized by means of NMR and IR spectroscopy, elemental analysis and X-ray structure analysis.
