Aryl triflinates are transformed to trifluoromethanesulfinylphenols in the presence of aluminum trichloride in dichloromethane at room temperature according to a thia-Fries rearrangement process. Rigorous exclusion of oxygen is necessary in order to avoid the formation of 2,2′-dihydroxybiaryls as secondary products
