By the hydrolysis of di(2-fluoro-2-polyfluoroalkyl-alkenyl)sulfones were obtained new 2,4-di(polyfluoroalkyl)-1,4-оxathiin-4,4-dioxides – a new type of fluorinated monocyclic 1,4-oxathiin derivatives. It was found that cycloaddition reactions of di(2-fluoro-2-polyfluoroalkyl-alkenyl)sulfones to diazomethane are accompanied with dehydrofluorination and produce new bispyrazolyl sulfones containing polyfluoroalkyl substituents at position 4 of pyrazole cycles.
