Bernd, Johannes published the artcileElectrochemical O-trifluoromethylation of electron-deficient phenols, Name: 4-Bromo-2,3,5,6-tetrafluorophenol, the publication is Electrochemistry Communications (2021), 107165, database is CAplus.
A simple and sustainable one-step strategy for the preparation of electron-deficient aryl trifluoromethyl ethers (ArOCF3) from the corresponding phenols by electrochem. synthesis is presented. Anodic oxidation of trifluoromethane sulfinate (Langlois reagent) leads to direct O-trifluoromethylation of phenol-derivatives bearing fluorine, chlorine, bromine and nitrile substituents under mild conditions in yields up to 75% and in gram-scale. This electrochem. protocol provides an economic and green synthesis for an otherwise inaccessible class of mols. without the need for expensive or toxic reagents, oxidants or metal catalysts.
