The reaction of [phenylthallium(III)(18-crown-6)] diperchlorate, [PhTlIII(18-crown-6)](Cl04)2 (1a), with phenol gives [phenyl(4′-hydroxyphenyl)thallium(III)(18-crown-6)] Perchlorate (2), the phenolic OH having remained intact. The complex la reacts also with alkylphenols, methoxyphenols, catechol, resorcinol, and pyrogallol to give thallated products exclusively at trie para position of the electron-donating group (OH or OCH3) without suffering from reduction of thallium (III). No reaction takes place with benzene, toluene, and tert-butylbenzene.
