| Popis: | 103 To extend the reactivity study of our previously developed five-coordinated iron(II) complex, Fe(BDPP) (1), and the reaction with nitric oxide generating high-spin non-heme {FeNO}7 complex, Fe(NO)(BDPP) (1-NO), ligand modifications 1-NO were carried out. By adding electron withdrawing functional groups, the redox potentials were tuned for better stability of nitrosyl complexes. 1-NO can only be stable at temperature below -100 °C, while modified Fe(NO)(BDPBrP) (2-NO) and Fe(NO)(BDPCF3P) (3-NO) can be stable at temperatures around 10 and 20 °C, respectively. Further, we confirmed the nitrosyl complexes by isotope (15NO) labeling experiments, spin multiplicity investigation by EPR spectra and density function theory. The formation of peroxynitrite on Fe(BDPBrP) complex was also explored. |
