trifluoromethylation of chlorinated and brominated phenolderivatives ClArOTs and BrArOTf gave chloro(bromo)trifluoromethylarenes through the chemoselective cleavage of Ar–O bonds. Furthermore, under similar reaction conditions, the chemoselective trifluoromethylation of Ar–Cl and Ar–Br bonds of ClArOPiv and BrArOTs was achieved to give trifluoromethylated phenolderivatives.
