Synthesis and coordination chemistry of ortho-perfluoroalkyl-derivatised triarylphosphines

Synthesis and coordination chemistry of fluorinated xanthate ligands

“…The classical routes to alkali metal xanthates, either in the absence of solvent or using an excess of the alcohol as the solvent, are not readily adaptable to the use of long chain perfluoroalcohols, and we used diethyl ether as a convenient, unreactive solvent for the synthesis of a series of long chain alkali metal xanthates (1)(2)(3)(4)(5); these offer convenient starting materials for the subsequent coordination chemistry. In the absence of structural and spectroscopic data for related long chain perprotioxanthate ligands and their coordination complexes, as part of this work potassium O-octylxanthate (1), with a C 8 H 17 sidechain, has been prepared and characterised.…”

“…We have been evaluating the electronic and steric implications of fluorine substituents on the donor properties of fluorinated ligands in coordination chemistry and the structural impact of these units on the solid state structures of the coordination compounds [1][2][3][4][5][6][7][8][9]. In contrast to the extensive coordination chemistry of fluorinated neutral P-, N-and O-donor ligands [10], there have been relatively few reports on charged fluorinated ligands.…”

Synthesis and coordination chemistry of perfluoroalkylated dithiophosphate ligands

“…We have been particularly interested in the electronic and steric implications of the perfluoroalkyl substituents on the donor properties of perfluoroalkylated ligands in coordination chemistry and the structural impact of the fluorous ponytails on the solidstate structures of the coordination compounds [5][6][7][8][9]. Although the coordination chemistry of perfluoroalkylated P-, N-and O-donor ligands has been extensively evaluated [4], there have been no recent examples of complexes incorporating S-donor ligands.…”

The synthesis and single-crystal X-ray structures of palladium(II) and platinum(II) complexes of the difluorovinyl and 1-chloro-2-fluorovinyl-substituted phosphines, PPh2(Z-CFCFH) and PPh2(E-CClCFH)

“…A similar conformation has been observed for the complex trans-[PdI 2 {PPh 2 (CH5 5CH 2 )} 2 ] [17], although in that case there is no asymmetry in the Pd-I bond lengths (2.5938(4) and 2.5939(4) Å ). The related platinum complex trans-[PtCl 2 {PPh 2 (2-C 6 H 4 C 6 F 13 )} 2 ] also displays this type of ligand conformation; in that case it was suggested that this was due to the additional number of FÁ Á ÁF interactions set up by this orientation of the ligands [20]. However, this appears not to be the case for 7 as there are no particularly short FÁ Á ÁF interactions in the extended structure.…”
