The C-H acyloxylation of polycyclic aromatic hydrocarbons (PAHs) is described. This reaction constructs aryl acyloxylate scaffolds from PAHs with equimolar hypervalent iodine compounds under mild reaction conditions. Interestingly, the blue light irradiation accelerated this transformation. Additionally, the synthesis of structurally new symmetric and unsymmetric diaroyloxylated fluoranthenes was accomplished with a ruthenium photoredox catalyst.
描述了多环芳烃（PAHs）的C-H酰氧基化反应。该反应在温和的反应条件下，使用等摩尔的高价碘化合物，从PAHs构建芳基酰氧基化物支架。有趣的是，蓝光照射加速了这种转化。此外，使用钌光氧化还原催化剂完成了结构新颖的对称和不对称二芳酰氧基化荧蒽的合成。
