Transition Metal Complexes With Perfluorinated Ligands.
Abstract
We have continued to make progress in preparing transition metal complexes containing fluorinated ligands, and have completed several sub-projects. We have prepared the first examples of transition metal compounds containing tetrafluoroethylene ligands that rotate rapidly on the NMR time scale. This is a significant discovery en route to a transition metal catalyst that will promote the Ziegler-Natta polymerization of fluorinated olefins to give high polymers. The factors governing the barrier to fluoroolefin rotation have been identified. We have synthesized the first example of a transition metal complex containing the pentafluorocyclopentadienyl ligand. This is an important ligand that may improve the thermal robustness of many transition metal compounds. (jg)
