Abstract

Encaged iron(II)-phthalocyanine, Fe(II)(Pc), was synthesized in Y zeolite. The adduct of Fe(II)(Pc) with pyridine was applied for catalyzing mild oxidation of hydroquinone to benzoquinone. 77 K Mössbauer spectra were recorded on the frozen reaction slurries. Comparisons of spectra of non-encaged Fe(Pc) with those of encaged Fe(Pc) without pyridine adduction are also done. Assignments for various iron containing species are proposed. Under oxygen atmosphere formation of the intermediate Oxy2Fe(II)(Pc)(Py) complex is suggested and during the following oxidation process stepwise removal of ligands is proposed.
