Cobalt‐Catalyzed Enantioselective Hydrotrifluoromethoxylation of Aromatic Alkenes

-containing substrates in the only two previous reports. Herein, we have developed a salen-Co-catalyzed enantioselective hydrotrifluoromethoxylation reaction involving aromatic alkenes and trifluoromethyl arylsulfonate (TFMS). This method effectively produces a range of chiral benzyl trifluoromethoxy compounds with enantiomeric excesses ranging from 75% to 99%.
