Bis(trifluoromethyl)sulfene, (CF 3 ) 2 C = SO 2 : Its Synthesis and Isolation as Amine Adduct Bis(trifluoromethyl)sulfene was obtained and stabilized as quinuclidine adduct 16 by three different methods: (1) by direct symmetrical splitting of the tetrakis(trifluoromethyl)‐1,3‐dithietane S‐oxides 11 and 18 as well as via the TAS salt 15 . The structure of 16 exhibits a C–S double bond. The quinuclidinium sulfonate 17 is formed under hydrolysis of 16 . In comparison, the corresponding pyridinium sulfonate 13 gives evidence also for the intermediate existence of the adduct 12 . The sulfonic acid 7 was prepared, but instead of the sulfonyl chloride 5 the sulfonyl chloride 6 was obtained from 7 and PCl 5 .
