We report herein a simple, additive- and metal-free, photoinduced, dual C-H/C-X borylation of chloro-, bromo-, and iodoarenes. The reaction produces 1,2- and 1,3-diborylarenes on gram scales under batch and continuous flow conditions. The regioselectivity of the dual C-H/C-X borylation is determined by the solvent and the substituents in the parent haloarenes.
我们在此报道了氯芳烃、溴芳烃和碘芳烃的简单、无添加剂和金属的光诱导双CH/CX硼化反应。该反应在间歇和连续流动条件下产生克级的 1,2- 和 1,3-二硼基芳烃。双CH/CX硼化反应的区域选择性由溶剂和母体卤代芳烃中的取代基决定。
