Reaction of Aromatics with Thallic Salts—Preparation of Arylthallic Compounds

Abstract
Arylthallic acetate perchlorate monohydrates, Ar-Tl(OAc)(ClO4)·H2O, were obtained as the major products of the reaction between thallic acetate and aromatics in acetic acid containing perchloric acid. As the minor products, various types of oxidation products including oxidative coupling were obtained. Reactivity order of the aromatics and the isomer distributions in the products were the same as those in the usual electrophilic aromatic substitution. With thallic nitrate, sulfate, and chloride, no arylthallic compounds could be obtained.
