Alkylations of 3-acylthio-4-aryl-3-isothiazoline-5-thiones with diazomethane, triethyloxonium tetrafluoroborate, or alkyl iodide afford 5-alkylthio-4-aryl-3-thioacyloxyisothiazoles, whereas the reactions of these isothiazolines with peracids or N-halosucc

Acylation of 4-aryl-3-mercapto-3-isothiazoline-5-thiones (1) with acid chloride in pyridine or alternatively with acid anhydride leads exclusively to 3-acylthio-4-aryl-3-isothiazoline-5-thiones (2).Reactions of (1) with reactive acetylenes afford 2-aryl(
