Cobalt-Catalyzed Trifluoromethylation–Peroxidation of Unactivated Alkenes with Sodium Trifluoro­methane­sulfinate and Hydroperoxide

Disclosed herein is an unprecedented cobalt-catalyzed trifluoromethylation–peroxidation of unactivated alkenes. In this process the hydroperoxide acts as a radical initiator as well as a coupling partner. The cheap and readily available sodium trifluoro­methane­sulfinate serves as the CF₃ source in the reaction. Various alkenes are transformed into vicinal trifluoromethyl-peroxide compounds in moderate to good yields
