Bispidine ligands iron oxidation

Fenton chemistry (320-322) and indicates that ferryl species (at least when supported by bispidine ligands) rather than OH radicals may be involved in substrate oxidation. For iron(II) aqua ions, this has also been proposed on the basis of DFT calculations (323), and a similar mechanism is confirmed by DFT calculations with the bispidine complexes (174). 

III.B.2), complexes with manganese, chromium, as well as second- and third-row transition metal ions (e.g., ruthenium) oxidation reactions with dioxygen alone or with other peroxides (e.g., ferf-butyl-peroxide) the stabilization and spectroscopic characterization of mononuclear superoxo, peroxo, and oxo complexes other catalytic processes (e.g., the iron-catalyzed aziridination), enantioselective reactions with chiral bispidine ligands and the iron oxidation chemistry continues to produce novel and exciting results.
