Abstract

Seven new substituted 5‐phenoxy‐1,2,4‐dithiazole‐3‐ones were prepared in modest yield (53–76%) from corresponding O‐phenyl thiocarbamates and chlorocarbonylsulfenyl chloride in dry ether at −10 °C. All of the compounds were characterized by NMR and elemental analysis and some of them by X‐ray diffraction. Preliminary kinetic measurements showed that the parent 5‐phenoxy‐1,2,4‐dithiazole‐3‐one is a very efficient sulfurizing agent toward triphenyl phosphite. J. Heterocyclic Chem., (2011)

## Abstract Previously unknown azomethylene derivatives of 4‐chloro‐5__H__‐1,2,3‐dithiazole 5–7 were synthesized by the reaction of the Appel salt 1 with __N__‐monosubstituted hydrazones 2–4. It was shown that they could be transformed into heterocyclic compounds 8–10.
