Quinizarin was first used as a photocatalyst for the oxidation of organic compounds with molecular oxygen in a supercritical carbon dioxide (SC-CO2) medium under the visible light irradiation. The choice of the catalyst was justified by the availability and high efficiency of quinizarin in comparison with structurally similar derivatives of anthraquinone: 2-nitro-1,4-dihydroxyanthraquinone and 2,3-diamino-1,4-dihydroxyanthraquinone. Carrying out photocatalytic synthesis of sulfoxides and sulfones via oxidation of organic sulfides with molecular oxygen in a SC-CO2 medium allows to reduce its fire hazard and make it environmentally benign.
