High Yields

The three-starting materials four-component reaction of (trifluoromethyl)alkenes, TBHP, and boronic acids is reported, delivering various useful α-trifluoromethyl-β-aryloxy tertiary alcohols in high yields and in an exclusively regioselective hydroetherification manner. TBHP serves as both the oxidants and the nucleophiles in this reaction, as well as the O-source of the products.
