Treatment of 2-methylphenols with chloro(diphenyl)-λ3- iodane led to their regioselective dearomatizing 2-phenylation into cyclohexa-2,4-dienone derivatives via a proposed ligand coupling reaction. In the same vein of investigation, treatment of 2-methylanilines with the λ5-iodane 2-iodoxybenzoic acid IBX reagent led to their regioselective dearomatization into previously undescribed ortho-quinol imines.

(Chemical Equation Presented) Dearomatization: Treatment of phenols and naphthols substituted at the ortho position by a small electron-donating group D with chlorodiphenyl-λ3-iodane leads to their regioselective ortho phenylation to give cyclohexa-2,4-dienone derivatives (see scheme). The mechanism of this reaction involves a nonradical direct coupling of the ligands.

The influence of the substituents on the phenol on the regiochemistry of the arylation reactions with Ph3BiCl2 and other bismuth reagents has been studied.O-Phenylation occurs with phenols substituted with electron-withdrawing groups.Electron-donating substituted phenols undergo ortho C-phenylation.Oxidative dimerisation has been observed with 2,6-dialkyl phenols.
