Abstract

An efficient halogenation reaction has been developed with diaryliodonium salts and cuprous halides. Various diaryliodonium salts 1 could perform the reaction with readily available CuBr or CuCl in CH₃CN at 80°C, assembling bromoarenes or chloroarenes in up to 92% yields. This provides us a method for the transformation from iodoarenes to other haloarenes.

Keywords: Diaryliodonium salts, Halogenation, Cuprous halide, Aromatic halides, Iodoarenes.
