Abstract

The Fe–halide bonds in Cp*Fe(dppe)X (X = F, Cl, Br, I) complexes are weakened as a consequence of one and two-electron oxidations; the bond weakening decreases in the order F << Cl < Br < I and is much less pronounced for F than the other halides, indicating a pronounced effect of apparent fluoride-to-metal backbonding as a consequence of the removal of electrons.
