An electrophilic trifluoromethylthiolation of allylic alcohols produces the corresponding allylic trifluoromethanesulfenates, which spontaneously rearrange into trifluoromethyl sulfoxides via a [2,3]-sigmatropic rearrangement. The reaction is straightforward and proceeds in good to high yields for the preparation of various allylictrifluoromethyl sulfoxides.

article described an unprecedented synthesis of trifluoromethylthiophosphonium salts from allyl trifluoromethyl sulfoxide and phosphines in the presence of trimethylsilyl trifluoromethanesulfonate (TMSOTf) through Mislow-Evans-type rearrangement. The resulting trifluoromethylthiophosphonium salts were firstly isolated and fully characterized. These fluoroalkylphosphonium salts, as exemplified by trifluoromethylthio
