SUPPORTED METALATED PHTHALOCYANINE AS CATALYST FOR OXIDATION BY MOLECULAR OXYGEN. SYNTHESIS OF QUINONES AND CARBONYL COMPOUNDS

ABSTRACT

Supported metalated phthalocyanine on K10 or on lamellar zirconium phosphate catalyses the oxidation of hydroquinones (and phenols) into quinones. Some interesting natural napthoquinones were also prepared (Juglone, Menadione, Lawsone, Phthiocol). Supported metalated phthalocyanine was also used in re-oxidation by oxygen of palladium and ruthenium, in the Wacker oxidation of olefins into ketones, in the oxidation of cyclohexadiene and in oxidation of benzylic alcohols in aldehydes.
