報道了由無金屬光催化劑 2-甲基蒽醌介導(dǎo)的溫和光催化 C-H 鍵選擇性氧化。 玻璃微通道反應(yīng)器可以增強反應(yīng)混合物對光子能量和氧氣的吸收，從而大大提高玻璃微通道反應(yīng)器中光催化反應(yīng)的反應(yīng)效率。 該反應(yīng)方法可以快速將烷基芳烴氧化成相應(yīng)的氧化產(chǎn)物，以高收率得到芳香酮。

A mild photocatalytic C-H bond selective oxidation mediated by metal-free photocatalyst 2-Methylanthraquinone was reported. Glass microchannel reactor can enhance the absorption of photon energy and oxygen by the reaction mixture, so as to greatly improve the reaction efficiency of photocatalytic reaction in glass microchannel reactor. This reaction method can quickly oxidize alkyl aromatics into corresponding oxidation products to obtain aromatic ketones in high yield.
