A　copper-mediated　trifluoromethylthiolation　of　vinyl　bromides　has　been　developed.　This　method　provides　ready　access　to　vinyl　trifluoromethyl　thioethers　in　good　to　high　yields　from　simple,　inexpensive　starting　materials.　A　broad　substrate　scope　is　achieved,　and　the　reaction　is　compatible　with　various　functional　groups,　including　cyano,　nitro,　trifluoromethyl,　alkoxy,　amino,　halide,　and　heterocyclic　groups.　©　2015　American　Chemical　Society.
