The Feâhalide 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.
Cp*Fe(dppe)X (X = F, Cl, Br, I) 络合物中的 Fe-卤化物键由于一电子和二电子氧化而减弱;键弱化按 F << Cl < Br < I 的顺序递减,并且 F 的键弱化程度远低于其他卤化物,这表明由于电子的去除,氟化物与
金属之间的反向键合具有明显的影响。
