Coordination chemistry and applications of medium/high oxidation state metal and non-metal fluoride and oxide-fluoride complexes with neutral donor ligands

Abstract Most high and medium oxidation state (O.S. ≥ 3) metal and non-metal fluorides and oxide fluorides have Lewis acidic properties, although detailed exploration of their chemistry with neutral ligands, which differs significantly from that with chloride, bromide or iodide co-ligands, has only been undertaken in recent years. The previous review (Benjamin et. al. Chem. Soc. Rev. 42 (2013) 1460) covered work published up to ∼2011, and the present article covers new work up to early 2019, a period which has seen many new contributions to the field. This article describes work on the coordination chemistry of d, f and p-block fluorides and oxide fluorides with neutral ligands containing donor atoms drawn from Groups 15 (N, P, As or Sb) and 16 (O, S, Se or Te) and including N-heterocyclic carbenes. The incorporation of the radionuclide 18 F into neutral metal complexes and their use in medical diagnosis via positron emission tomography (PET) is also described, along with briefer coverage of other potential applications.
