Kb. Jensen et al., Deprotonation of low-spin mononuclear iron(III)-hydroperoxide complexes give transient blue species assigned to high-spin iron(III)-peroxide complexes, CHEM COMMUN, (14), 1999, pp. 1313-1314
Purple iron(III)-hydroperoxide complex ions [Fe(Rtpen)(eta(1)-OOH)](2+) can
be reversibly deprotonated to give transient blue species showing spectros
copic properties consistent with iron(III)-peroxide complexes; a novel ferr
yl species is produced in MS/MS experiments with the iron(III) hydroperoxid
e ion.
