Abstract

Abstract The halogenation of aromatic compounds with halide cations generated from halogen and silver perchlorate under anhydrous conditions is generally known as Birckenbach‐Goubeau halogenation. Many aryl aliphatic acids have been found to be halogenated especially when silver acetate is employed as the silver salt and acetic acid as the reaction medium. Besides this halogen cations can also be produced by mixing halogen with other metal halides. Mixture of bromine and silver acetate is found to be an effective aromatic bromination agent. This reaction can be used to prepare brominated or iodinated aromatic compounds or dihaloalkanes.
