Novel reactions of perfluoro-2-(trifluoromethyl)-propene

Synthetic Methods for Compounds Having CF3–S Units on Carbon by Trifluoromethylation, Trifluoromethylthiolation, Triflylation, and Related Reactions

“…Vinyl trifluoromethyl sulfide can be prepared by the trifluoromethanesulfenylation of different substrates. The reaction of vinyl bromide with CuSCF 3 gave the corresponding trifluoromethyl sulfides (eqs a and b, Scheme ). , For the gem -dibromovinyl substrate, both monosubstituted and bisubstituted products were obtained (eq b, Scheme ) . Copper-catalyzed trifluoromethanesulfenylation of vinyl boronic acids with nucleophilic or electrophilic trifluoromethanesulfenylating reagents was reported by Vicic (eq c, Scheme ) and Shen (eq d, Scheme ), respectively.…”
