Heterogeneous photocatalytic oxidation of naphthalenes on zirconium and germanium phosphates

Irradiated zirconium and germanium phosphates are used as photocatalysts for the oxidation of electron-rich molecules of naphthalenes in air-saturated acetonitrile. Some of these reactions are selective: phthalic anhydride is the main reaction product (yield 70%) in the photooxidation of naphthalene...

Description
Summary:Irradiated zirconium and germanium phosphates are used as photocatalysts for the oxidation of electron-rich molecules of naphthalenes in air-saturated acetonitrile. Some of these reactions are selective: phthalic anhydride is the main reaction product (yield 70%) in the photooxidation of naphthalene. A mechanism involving the formation of radical cations via the interaction of naphthalene with irradiated zirconium phosphate and a likely scheme of reaction are proposed.
