Preparation and Reactivity of Anionic Iron Sandwich Complex Bearing π‐Phenol Ligand Acting as Proton‐Coupled Electron Transfer Reagent
A neutral Fe(II) sandwich complex bearing a π-phenol ligand with a trifluoroborate substituent [Cp*Fe(η<sup>6</sup>-2-<sup>t</sup>Bu-6-BF<sub>3</sub>-C<sub>6</sub>H<sub>3</sub>OH)] is designed and prepared, which affords the corresponding anionic Fe(I) sandwich complex [Cp*Fe(η<sup>6</sup>-2-<sup>t</sup>Bu-6-BF<sub>3</sub>-C<sub>6</sub>H<sub>3</sub>OH)]<sup>-</sup> with an effective O-H bond dissociation free energy at 40.7 kcal/mol in tetrahydrofuran on treatment with KC<sub>8</sub>. The anionic complex acts as a proton-coupled electron transfer reagent for the reduction of organic substrates such as acetophenone and anthracene, whereas the reaction with a Mo(IV) nitride complex leads to the stoichiometric formation of ammonia.
