Reactions of allyl alcohols and boronic acids with trifluoromethanesulfonyl hypervalent iodonium ylide under copper-catalysis†
Trifluoromethylsulfinyl and trifluoromethylthio groups are both important substituents for pharmaceuticals, agrochemicals and functional materials. We herein report the trifluoromethylthiolation of allyl alcohols 2 with trifluoromethanesulfonyl hypervalent iodonium ylide 1 under copper catalysis to provide trifluoromethylsulfinyl compounds 3. Trifluoromethylthiolation of boronic acids 4 with 1 furnished trifluoromethylthio compounds 5.
