Optimization of the Synthesis of Salts [V10O28]6– for the Preparation of [VO2(DMSO)4](CF3SO3) and Its Immobilization on Polyethylene Terephthalate for Catalytic Applications

Abstract Aspects of the synthesis and isolation of (Bu4N)3[H3V10O28] (I) and Na6[V10O28]·18H2O (II) from one reaction mixture are considered. The procedure for the synthesis of compound I is optimized. The reaction of compound I and HSO3CF3 in dimethyl sulfoxide (DMSO) affords complex [VO2(DMSO)4](CF3-SO3) (III). A possibility of using complex III for the preparation of catalytically active materials based on polyethylene terephthalate (PET) is shown.
