Synthesis and Reduction Potentials of Lanthanide Fluoroalkoxides
MetadataShow full item record
The syntheses and reduction potentials of the lanthanide fluoroalkoxides [K][La(OC4F9)4(THF)2] and [K][La(pinF)2(THF)3] (Ln = La3+, Sm3+, Ce3+; HOC4F9 = perfluorotertbutanol; pinF = perfluoropinacol) are presented. A preliminary investigation of the influence of fluorinated ligand environments on redox behaviors of lanthanides was pursued. Both complexes were synthesized by a Brønsted–Lowry acid-base reaction from an Ln[N(SiMe-3)2]3(THF)n precursor. Air-free cyclic voltammetry with a ferrocene/ferrocenium internal reference and single-crystal X-ray diffractometry were employed to characterize the reductive potentials and structural information for these materials.
