Аннотация:
In the presence of oxygen atom donors [XO, e.g., m-chloroperbenzoic acid (m-CPBA), o-tert-butylsulfone iodosyl benzene (ArIO)] the benzyl group of the ligand in a mixed-valent Fe<sup>ii</sup>Fe<sup>iii</sup> complex is almost quantitatively ortho-hydroxylated to a phenolate terminally bound to one iron in the derived Fe<sup>iii</sup>Fe<sup>iii</sup> complex. All available experimental evidence concurs to suggest that this reaction involves an oxo-Fe<sup>iv</sup>Fe<sup>iv</sup> intermediate.
