Synthesis, Characterization, and Reactivity of Thioether-Ligated Organoiron(II) Complexes


Abstract In this work we report a series of four-coordinate organoiron(II) complexes in a sulfur-rich ligand environment. The high-spin, S = 2, compounds [PhTttBu]Fe(R) (R = Et, Ph, Mes, Bn, CH2SiMe3) (Mes = 2,4,6-Me3C6H2; Bn = CH2C6H5) [PhTttBu]− = (phenyltris((tert-butylthio)methyl)borate) bearing an anionic tripodal thioether ligand were synthesized and characterized by NMR spectroscopy and structurally characterized by single-crystal X-ray crystallography. Exposure of [PhTttBu]Fe(R) (R = Me, Et, Ph, CH2SiMe3) to 1 atm of CO afforded diamagnetic, six-coordinate complexes [PhTttBu]Fe(CO)2(R). The carbonylation of [PhTttBu]Fe(R) (R = Bn, Mes) formed two Fe products: [PhTttBu]Fe(CO)2(R), and a five-coordinate, low-spin, S = 1/2, [PhTttBu]Fe(CO)2, the latter due to homolytic Fe–C bond cleavage.
