Chloro(oxo)methanesulfenyl chloride (ClCOSCl) is very versatile substrate for the synthesis of thiazolidinones (e.g., 338) and benzothiazolones. It can be used in reaction with N-alkylanilines,[‌553‌] primary and secondary enamines,[‌554‌‌556‌] and substituted pyrimidines (Scheme 242).[‌557‌] Several different substituted thiazolidinones and benzothiazolones are obtained in moderate to high yields. Chloro(oxo)methanesulfenyl chloride can be readily obtained by reaction of trichloromethanesulfenyl chloride with concentrated sulfuric acid.
