✦ Synopsis

3,3,4-hexafluoro-l,3-dithietane (7~1, 2-chloro-1,1,2,4,4-pentafluoro-3,3-dioxo-l,3-dithietane (9b), 2,4-dichloro-1,1,2,4-tetrafluoro-3,3-dioxo-l,3-dithietane (SC), and 1,1,2,2,4,4-hexafluoro-3-oxo-1,3-dithietane (14) were synthesized by liquid-phase/low-temperature fluorination or with xenon difluoride. They were characterized by elemental analysis, MS-, NMR-and IR-spectroscopy. New syntheses of 2,2,4,4-tetrafluoro-1,3-dioxo-1,3-dithietane (12) and 1,1,2,2,4,4-hexafluoro-3,3-dioxo-1,3-dithietane (3) are reported. ZUSAMMENFASSUNG 2-Chlor-1,1,2,3,3,4,4,-heptafluor-1,3-dithietan (7b), 2,4-Dichlor-1,1,2,3,3,4-hexafluor-1,3-dithietan (7c), 2-Chlor-1,1,2,4,4-pentafluor-3,3-dioxo-l,3-dithietan (9b), 2,4-Dichlor-1,1,2,4-tetrafluor-3,3-dioxo-l,3-dithietan (SC), und 1,1,2,2,4,4-Hexafluor-3-oxo-1,3-dithietan (14) wurden mittels Fltissigphasen-Tieftemperaturfluorierung bzw.
