The SIV spirosulfurane 19 and the lactam-sulfoxides 21, 22 and 23 with seven-, eight- and nine-membered rings have been prepared by oxidation and dehydration of trifluoroacetylaminoarylcarboxyphenyl sulfides and sulfoxides, respectively.A mechanism is proposed for the formations of lactam-sulfoxides.The preparation of the starting sulfides and sulfoxides is also described. Key words: Diaryl sulfides; diaryl sulfoxides; spirosulfurane; lactams; carboxyl activation; lactam-sulfoxide formation.
