compound, i.e., 2-iodobenzoic acid (2-IB), selectively yields p-quinones from monomethoxyarenes under mild conditions. In this reaction system, an organoiodine compound is immediately oxidized by Oxone® to generate cyclic hypervalent iodine (III) species in situ, which serves as the specific mediator for the selective p-quinone synthesis, preventing o-quinone formation.
我们发现Oxoxon®与有机碘化合物(即2-碘苯甲酸(2-IB))的组合在温和条件下选择性地从单甲氧基芳烃中生成了对醌。在该反应体系中,有机碘化合物立即被氧化的冰冷生成环状高价碘(III)物质在原位,作为具体的介体用于选择性p -quinone合成,阻止ö -quinone形成。
