Novel Mn(III) Porphyrins and Prospects of Their Application in Catalysis

Аннотация

Four novel Mn(III) porphyrins have been synthesized and characterized by UV-Vis, IR, ESI-mass spectroscopy, elemental analysis, magnetic susceptibility studies, TLC, and conductivity measurements. The tentative structure has been proposed. Depolymerization of coal using the synthesized Mn(III) porphyrins have been demonstrated by the optical density method using humic acid as a model of coal. The synthesized complexes have shown excellent depolymerization activity based on comparative studies. Complexes have been successfully applied for the catalytic oxidation of benzyl alcohol, aniline, benzoin, and benzaldehyde into benzaldehyde, nitrobenzene, benzil, and benzoic acid, respectively, at room temperature and pressure.
