1,3,4-Oxathiazoles, on thermolysis, undergo retro-1,3-dipolar cycloaddition to afford carbonyl compounds and nitrilesulphides, which may be trapped by cycloaddition with alkynes and nitriles.

Nitrilesulphides, generated by thermolysis of 1,3,4-oxathiazol-2-ones, undergo 1,3-dipolar cycloaddition to activated carbonyl groups yielding 1,3,4-oxathiazoles.
