The difunctionalization of alkenes involving a trifluoromethylthio group (SCF3) for the conversion of versatile and readily available olefins into structurally more complex molecules has been successfully studied. However, the disproportionate dithiolation of alkenes is unknown. Herein, a transition-metal-free protocol is presented for the vicinal trifluoromethylthio–thiolation of unactivated alkenes via a radical process under mild conditions with a broad substrate scope and excellent tolerance.

A transition-metal-free visible-light photoredox-catalyzed decarboxylative alkylation of benzylic C-(sp3)−H bonds of N-aryl tetrahydroisoquinolines is reported. The developed methodology tolerates various functional groups and proceeds smoothly without the requirement of stoichiometric oxidants. A preliminary mechanistic study indicated that a radical process is involved in the reaction.

The difunctionalization of alkenes involving trifluoromethylthio group (SCF3) for the conversion of versatile and readily available olefins into more structurally complex molecules has been greatly studied. However, the disproportionate dithiolation of alkene is unknown. Herein, a transition-metal-free protocol is presented for vicinal trifluoromethylthio-thiolation of unactivated alkenes via a radical process under mild condition with broad substrate scope and excellent tolerance.
