Extending the previous use of tert-butyl sulfoxide as the sulfinyl source, intramolecular sulfinylation of sulfonamides was successfully performed. The resulting sulfinimides were not isolated and instead were believed to go through an all-heteroatom Wittig-equivalent process to eventually afford aryl[4,5]isothiazoles in high yields.
