Chen, Fei published the artcileCopper/β-diketone-catalysed N-arylation of carbazoles, Recommanded Product: 9-(4-Fluorophenyl)-9H-carbazole, the publication is RSC Advances (2015), 5(64), 51512-51523, database is CAplus.
A wide range of aryl iodides RC6H4I (R = H, 4-Cl, 3-CH3, 2-Br, etc.) and carbazoles I [R1 = H, 3-C(CH3)3, 3-Br, 2-Br; R2 = H, 6-C(CH3)3, 7-Br, 6-Br] can be coupled to generate N-arylcarbazoles II in the presence of copper-catalyst. Several com. available ligands such as β-diketone and diamine, are tested in the N-arylation of carbazoles I. The catalytic system generated in situ from an inexpensive copper salt, simple β-diketone and inorganic base efficiently N-arylated the carbazoles I. However, the sterically hindered effect of aryl iodides is evident in this catalytic system. The selectivity of two iodine atoms on the aromatic ring of diiodobenzene R3C6H4I (R3 = 4-I, 3-I, 1-Br-2-F) is evaluated in the developed catalytic system. Results showed that the selectivity of diiodobenzene can be tuned by the reaction temperature
