Mild Conditions

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.
