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

Asymmetric electrophilic fluorination of difluoroalkenes remains undeveloped because the poor reactivity with electrophiles. However, such reactions, if feasible, are expected to be useful for synthesis chiral heterocyclic compounds a trifluoromethyl group at stereogenic center. In this Letter, we disclose first example asymmetric fluoroamide cyclization using our dianionic phase-transfer catalyst. This reaction provides unique trifluoromethylated oxazoline derivatives synthetically level.
