Visible-Light-Mediated Addition Reactions of Sulfur-Containing Reagents with α-Trifluoromethyl Alkenes

Herein, we described the addition reactions of sulfur-containing reagents (sodium sulfinates, dithiosulfonates) with α-trifluoromethyl alkenes under visible light. A series of trifluoromethyl sulfonates were synthesized via the visible-light-induced radical addition reaction of sodium sulfinates and α-trifluoromethyl alkenes to obtain protons from the solvent. A series of dithiosulfonated derivatives were synthesized via visible-light-induced bifunctionalization reaction of α-trifluoromethyl alkenes with dithiosulfonates.This strategy has the advantages of mild reaction conditions, good substrate universality and high yield up to 99% yield.
