Regioselective Halogenation of Arenes and Heterocycles in Hexafluoroisopropanol

Tang, Ren-Jin,Milcent, Thierry,Crousse, Benoit

, p. 930 - 938 (2018/01/28)

Regioselective halogenation of arenes and heterocycles with N-halosuccinimides in fluorinated alcohols is disclosed. Under mild condition reactions, a wide diversity of halogenated arenes are obtained in good yields with high regioselectivity. Additionally, the versatility of the method is demonstrated by the development of one-pot sequential halogenation and halogenation-Suzuki cross-coupling reactions.
