2-Dichloro-3,3-bis(trifluoromethyl) thiirane 4 and 2- chloro-2-fluoro-3,3-bis(trifluoromethyl) thiirane 5 were synthesized by the reaction of bis(trifluoromethyl)diazomethane 1 with thiophosgene 2 or chlorofluorothiocarbonyl 3. Starting from the 1,3-dithietanes 6 and 10 the 1,3-dithietane-S-oxides 7, 8, 11 and 13 could be obtained by use of various oxidation agents. 2,3-Dichloro-2,3-bis(trifluoromethyl) thiirane
