The iron(III) chloride-catalyzed Friedel–Crafts arylation of 4-aryl-4-methoxy-2,5-cyclohexadienones, which were easily prepared by the phenyliodine(III) diacetate (PIDA)-mediated oxidation of 4-arylphenols in methanol, proceeded site-selectively to form meta-terphenyl (2,4-diarylphenol) derivatives in good yields. The subsequent PIDA-mediated oxidation and iron(III) chloride-catalyzed Friedel–Crafts arylation of the resulting products gave the corresponding 2,4,6-triarylphenol derivatives. The present method provides useful highly substituted polyarylated compounds. (Figure presented.).

Generation of the 4-biphenylyloxenium ion, 1a, from hydrolysis of 4-acetoxy-4-phenyl-2,5-cyclohexadienone, 2a, is demonstrated by common ion rate depression and azide trapping. The ion is less selective with a shorter lifetime (12 ns at 30 °C) in aqueous

The oxidation of eight substituted anilines with lead tetraacetate gives azo derivatives and products deriving from nucleophilic nuclear attack.A ligand transfer mechanism and a reaction path via aminium radical is suggested for these oxidations.
