Organocatalytic 1,5-trifluomethylthio-sulfonylation of vinylcyclopropane mediated by visible light in water phase

The 1,2-difunctionalization has developed into a robust tool for preparation of the complex organic molecules, and remote difunctionalization has also aroused widespread interest to achieve pluripotency of the difunctionalization. Herein, we report a metal-free organocatalytic system mediated by visible light to realize the remote 1,5-trifluomethylthio-sulfonylation of vinylcyclopropane with ArSO2SCF3 reagents in water phase. This reaction exhibits broad functional groups compatibility, moderate to good yields, as well as high regioselectivities and stereoselectivities.
