abstract
A terminal palladium (II) fluoride complex (FPNP)PdF (where FPNP is a an anionic fluoro-substituted diarylamido/bis(phosphine) pincer ligand) has been prepared and characterized spectroscopically and structurally. An X-ray diffraction study revealed an approximately square-planar environment about Pd and a short Pd-F bond distance. (FPNP)PdF reacted with silanes containing electron-withdrawing groups on Si by exchange of fluoride with one of the substituents on Si. An analysis of the 19F chemical shifts of both the Pd-bound fluoride and of the fluorines on the backbone of the FPNP ligand is provided. 2010 Elsevier B.V.
