Sulfonyl-1,2,4-triazole salts

Abstract

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.

1 . Process of fluorination of a compound, said process comprising reacting in a solvent said compound and a fluorinating agent, wherein said compound is a delocalized anion of formula ClSO 2 —X − —SO 2 Cl, wherein X −  is an anionic center and said fluorinating agent comprises an ionic fluoride of a divalent cation. 
     
     
         2 . A process according to  claim 1 , wherein said fluorination agent comprises ZnF 2 . 
     
     
         3 . A process according to  claim 1 , wherein said solvent is an organic solvent. 
     
     
         4 . A process according to  claim 1 , wherein said anionic center comprises N − .
