摘要：

The reaction of a gamma,gamma,gamma-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.
