Abstract

Aryl halides are important synthetic intermediates that have been used extensively in various carbon–carbon and carbon–heteroatom bond-forming reactions. 1 The traditional aromatic halogenation includes electrophilic aromatic substitution and conversion of an amine into a halide via the diazonium salt (ie, the Sandmeyer reaction). 2 Although the electrophilic aromatic halogenation works well for the preparation of chloroarenes and bromoarenes, the direct iodination of arenes with ...
