Abstract
Abstract The review presents a comparative analysis of promising homogeneous metal complex catalysts and the results of studies on the synthesis and determination of the structural characteristics of efficient catalysts for the oxidation of organic compounds with hydrogen peroxide Q3{PO4[WO(O2)2]4} (Q is the quaternary ammonium cation) by EXAFS, SAXS, NMR, Raman, and IR spectroscopy. The possibilities of using bifunctional homogeneous peroxopolyoxo metal complexes in combination with organic cations having quaternized nitrogen under conditions of phase transfer catalysis were considered using as an example the oxidation of organic compounds of various classes with hydrogen peroxide, forming aliphatic and aromatic epoxides, mono- and dicarboxylic acids, as well as biologically active compounds for medical and agroindustrial purposes.
