The article was titled 《BF3·Et2O-Promoted Aerobic Bromination of Heteroarenes with LiBr as the Bromination Sources》. The information in the text is summarized as follows:
Aromatic bromination of heteroarenes, e.g., 10H-phenothiazine has been accomplished by using readily available LiBr with the aid of BF3·Et2O under mild aerobic conditions. The broad substrates scope of the reaction is compatible with the optimized condition, and excellent functional-group is well tolerated in this transformation. The gram-scale preparation of aromatic bromides RBr (R = 3-methyl-5-phenyl-1H-pyrazol-4-yl, 9H-carbazol-3-yl) exhibits good reaction efficiency. Meanwhile, the dibromination of heteroarenes I (R1 = H, CH3; R2 = H, OCH3, Cl) delivers the polybromo-aromatic compounds II in good yields. The experimental process involved the reaction of 3,6-Dibromo-9H-carbazole(cas: 6825-20-3HPLC of Formula: 6825-20-3)
3,6-Dibromo-9H-carbazole(cas: 6825-20-3) is used as a reagent in the synthesis of P7C3-A20 which is a potent neuroprotective agent. And it has been used in the preparation of N-(2-hydroxyethyl)-3,6-dibromocarbazole.HPLC of Formula: 6825-20-3
