Abstract

The reaction of a g,g,g-trifluoro-b-(p-methoxyphenylamino) sulfoxide with trifluoroacetic anhydride under Pummerer conditions occurs in an abnormal fashion, providing an excellent yield of the cyclic six-membered sulfonium salt arising from intramolecular interception of the usual trifluoroacetoxy-sulfonium intermediate by the electron rich p-methoxyphenyl group.
