Oxidation of Ce[N(SiMe3)2]3 in the presence of PF6– or BF4– afforded isolation
of CeF[N(SiMe3)2]3. Structural and
electrochemical characterization shows that this compound is in its
tetravalent oxidation state and contains a terminal fluoride ligand.
Spectroscopy and density functional theory have been used to characterize
the Ce–F bond as ionic, which is reinforced by an initial reactivity
study that demonstrates the nucleophilicity of the fluoride ligand.
