    Description / Table of Contents: Synthesis and Properties of New Perhalogenated 1,3-Dithietane S-Oxides, Thiiranes, and SulfinesThe series of new tetrabromo-1,3-dithietane S-oxides 2, 3, 6, and 7 were synthesized, and the dibromosulfine 4 could be obtained from the 1,3-dioxide 3. The oxidation of 1,3-dithietane-2-one 12 yields dichlorosulfine 8, whereas 14, gives no difluorosulfine. From the hitherto unknown 2,2,4-trichloro-4-fluoro-1,3-dithietane (21) the 4-chloro-4-fluoro-1,3-dithietane-2-one (22) was prepared as a potential sulfine precursor. A convenient synthesis of tetrachlorothiirane (16) from tetrachloro-1,3-dithietane 1,1-dioxide (13) by thermolysis is reported.
    Notes: Die Reihe neuer Tetrabrom-1,3-dithietan-S-oxide 2, 3, 6 und 7 wurden synthetisiert, und, ausgehend vom 1,3-Dioxid 3, konnte das Dibromsulfin 4 erhalten werden. Die Oxidation des 1,3-Dithietan-2-ons 12 ergab Dichlorsulfin 8, die von 14 jedoch nicht das Difluorsulfin. Ausgehend vom bisher unbekannten 2,2,4-Trichlor-4-fluor-1,3-dithietan (21) wurde das 4-Chlor-4-flour-1,3-dithietan-2-on (22) als potentielles Sulfin-Vorprodukt dargestellt. Eine günstige Synthesemethode für Tetrachlorthiiran (16) aus Tetrachlor-1,3-dithietan-1,1-dioxid (13) durch Thermolyse wird beschrieben.
