摘要:A process is provided by which fluorinated unsaturated compounds that were difficultly synthesizable or prepared by uneconomical synthesis processes can be prepared from inexpensive and easily available raw materials in a short step in high yield. Fluorinated unsaturated compounds (2): R?AFOCRBF=CF¿2 can be prepared by pyrolysis of compounds (1): R?AFOCFRBFCF¿2COF, wherein RAF is a monovalent organic group stable to pyrolysis, and RBF is a monovalent organic group stable to pyrolysis or fluoro, or alternatively R?AF and RBF¿ may be united to form a divalent organic group stable to pyrolysis.

标 题:Sulphonyl-1,2,4-triazole salts
发明人：MICHOT CHRISTOPHE
权利人:PHOSTECH LITHIUM INC; UNIV MONTREAL
摘要:The invention relates to triazole salts, to their preparation and to applications thereof. The salts have at least one anionic triazolium group which carries at least one chlorosulphonyl, fluorosulphonyl or alkoxyfluorosulphonyl group, each of the anionic groups being combined with a proton or a cation that has a valency of less than or equal to 4. The salts are useful as synthesis reagents, as chemical-reaction or polymerization catalysts, and as ion-conducting materials for electrochemical generators, supercapacitors and electrochromic devices.
