Реферат:
Using EPR and H1 NMR spectroscopy, ferric species formed in the iron picolinate/(pyridine/acetic acid)/HOOH catalytic system for the direct ketonization of methylenic carbons were characterized. The initial complex K[FeII(PA)3] (PA-pyridine-2-carboxylato) converts into mononuclear hydroxo complex FeIII(PA)2(OH)Py via interaction with equimolar amount of HOOH in 2:1 Py/AcOH molar mixture. Addition of the great excess of HOOH to the solution of FeIII(PA)2(OH)Py in 2:1 Py/AcOH at 253 K gives rise to the formation of the unstable high-spin ferric peroxo complex with suggested structure FeIII(PA)2(OOH)Py. This complex is supposed to be reactive intermediate of oxidation.
