The potassium salt [K([18]crown-6)(THF)2][Cp*Fe(η4-2,4,6-triphenylphosphinine)}] (K1, Cp* = C5Me5) can be isolated in 68% yield by reacting the anionic naphthalene complex [K([18]crown-6){Cp*Fe(η4-C10H8)}] (C10H8= naphthalene) with 2,4,6-triphenylphosphinine. CompoundK1reacts with water to afford [K([18]-crown-6)]{Cp*Fe(η4-2,4,6-triphenyl-2,3-dihydrophosphinine 1-oxide)}] (K2) with a novel 2,3-dihydrophosphinine 1-oxide ligand. Oxidation ofK1with one equivalent of ferrocenium hexafluorophosphate yields the P–P-bonded diphosphinine complex [Cp*Fe(η5-2,4,6-triphenylphosphinine)]2(3), while the iodide salt [Cp*Fe(η6-2,4,6-triphenylphosphinine)]I (4) can be obtained by reactingK1with one equivalent of iodine. Reactions of4with LiNMe2, Cp*Li, LiBHEt3, and Ga(nacnacDipp) (nacnacDipp= HC{C(Me)N(C6H3-2,6-iPr2)}2) afford [Cp*Fe(η5-1-dimethylamino-2,4,6-triphenylphosphacyclohexadienyl)] (5), [Cp*Fe(η5-1-(η1-Cp*)-2,4,6-triphenylphosphacyclohexadienyl)] (6), [Cp*Fe(η5-1-hydro-2,4,6-triphenylphosphacyclohexadienyl)] (7), and [Cp*Fe((η5-1-{Ga(nacnacDipp)I}-2,4,6-triphenylphosphacyclohexadienyl] (8). The molecular structures of5–8display η5-coordinated λ3σ3-phosphinine anions. All new complexes were fully characterized by spectroscopic techniques (1H,13C, and31P NMR, UV–vis, and IR spectroscopy), elemental analysis, and X-ray crystallography. The electronic structures of these new phosphinine complexes were investigated theoretically at the DFT level, using molecular orbital and population analyses. The nature of the electronic transitions observed in the UV–vis spectra was analyzed using TD-DFT calculations.
