Реферат: 9,10-Anthraquinone and its derivatives are the valuable products of organic synthesis. We developed one-pot processes for the preparation of substituted anthraquinones via diene synthesis in the presence of heteropoly acid H17P3Mo16V10O89 (HPA-10) solution as a bifunctional catalyst, i.e., acidic catalyst for diene synthesis and catalyst for the oxidation of the obtained adduct. In the present study, experimental data were obtained for two one-pot processes: 1) 2-methylanthraquinone (2-MAQ) synthesis from naphthoquinone (NQ) and isoprene; 2) 2,3-dimethylanthraquinone (2,3-ДМАQ) synthesis from NQ and 2,3-dimethyl-butadiene. We investigated the possibility of multicycle catalyst performance. After the desired reaction, the HPA-10 solution was rapidly regenerated in separate stage and reused. Various methods for regeneration of the catalyst were alternated.
