ortho-preferred, radical alkylation of electron-deficient (hetero)arenes is reported. A variety of electron-deficient arenes were shown to react with various primary alkyl sources, producing the alkylated (hetero)arenes in good yields. This reaction might be an alkyl radical, nucleophilic aromatic substitution reaction, rather than the traditional electrophilic Friedel–Crafts reaction. HOMO–LUMO analysis and
报道了缺电子(杂)芳烃的非传统铁催化的,邻位优选的自由基烷基化。已显示出各种电子不足的芳烃可与各种伯烷基源反应,以高收率生产烷基化(杂)芳烃。该反应可能是烷基自由基,亲核芳香取代反应,而不是传统的亲电Friedel-Crafts反应。关于区域选择性的关键过渡态的HOMO-LUMO分析和DFT研究与观察到的反应和结论一致。
