Bis(trifluoromethylthio)ketene (CF3S)2C=C=O has been synthesized by dehydration of (CF3S)2CHC(O)OH or HCl elimination from (CF3S)2CHC(O)Cl and fully characterized. Some reactions of the ketene are presented.
双(三氟甲硫基)乙烯酮(CF 3 S)2 C = C = O是通过(CF 3 S)2 CHC(O)OH脱水或从(CF 3 S)2 CHC(O)Cl完全去除HCl合成的表征。介绍了烯酮的一些反应。

Reaction of potassium fluoride or tetramethylammonium fluoride with thiophosgene leads to the formation of a nucleophilic source of trifluoromethanethiolate, suitable for the preparation of trifluoromethyl aryl sulfides from activated haloaromatics. Analysis of the byproducts in the system demonstrates that complex molecules with up to C-4 chains may be formed by the reaction of fluoride salts with thiophosgene. (C) 1999 Elsevier Science S.A.
