Organometallic fluorides can serve as a source of organofluorine compounds. Organofluorine chemistry impacts many areas of everyday life and technology. The C-F bond is present in several pharmaceuticals, agrichemicals, fluoropolymers, refrigerants, surfactants, anesthetics, oil-repellents, catalysts, and water-repellents. Organofluorine ligands play a key role in organometallic and coordination chemistry. The organofluorine compounds serve as a sigma-donor ligand, as in the case of [(C5Me5)2Ti(FC6H5)]BPh4. Organometallic fluorides are also useful in organic transformations, and as shift reagents in NMR spectroscopy.
At the interface of coordination chemistry and materials science, the fluorination of organic ligands is used to tune the properties of component molecules. For instance, the extent and position of the fluorination of metalated 2-phenylpyridine ligands in platinum(II) complexes influence their optical properties. Fluoroalkyl-substituted tin hydrides, which are used for reductions involving fluorous technology, give products which are easily separated from the spent tin reagent by extraction using fluorinated solvents. Both tetrakis(pentafluorophenyl)borate, B(C6F5)4-, and the related tetrakis(3,5-bis(trifluoromethyl)phenyl)borate, are useful in Ziegler-Natta catalysis and the associated alkene polymerization methodologies. Commercial secondary batteries such as lithium-ion cells employ lithium hexafluorophosphate.
Organometallic fluorides of Group 4 metals are efficient catalysts for polymerization (Advances in catalysis; Gates, B.C., Knoezinger, H., Jentoft, F., Eds.; Volume 54; Elsevier: Amsterdam, 2011).
