Mechanism of formation of o-semiquinone metal complexes under mechanical pulse action on metal oxide-quinone-pyrocatechol systems

The possibility of the mechanochemical synthesis of metal-containing mono-, bi-, and triradicals under mechanical pulse action on mixtures of metal ox ides (CuO, ZnO, CdO, PbO, Al2O3, Ga2O3, Sb2O3, Bi2O3, Cr2O3, TiO2, GeO2, Zr O2, or SnO2) with quinone and pyrocatechol was examined. The reaction produ cts are formed both on the surface of metal oxides and as individual solid phases. The mechanism of chemical processes that occur under the action of a single elastic wave pulse is proposed.
