Organoboron thermally activated delayed fluorescence molecules (DABNA) were employed as photoredox catalysts. A series of DABNA analogs were synthesized by regioselective one-shot borylation, which were then applied to photoredox catalyzed dehalogenation of aryl halides. Under the radiation of blue LED, the dechlorination of aryl chloride proceeded in moderate yield. Furthermore, by using DOBNA bearing oxygen atoms in place of nitrogen atoms, the reductive cyclization of nitroaromatic compounds was achieved to afford carbazole in good yields at room temperature.
