<p>The invention concerns a fluorination method for obtaining fluorinated compounds. The method consists in reacting with an ionic fluoride of a monovalent cation a compound of formula (I), wherein: M represents H, an alkaline metal, a quaternary phosphonium group or a quaternary ammonium group; Y represents SO2, and m is 1, or Y is PO and m is 2; Z represents CR2, N or P; R1 represents a carbonaceous and/or electron-attracting group which has a Hammet parameter σ¿P? higher than 0.4; R?2¿ represents a carbonaceous and/or electron-attracting group; X represents a halogen other than a fluorine. The fluorinated compounds obtained are useful in particular as electrolyte in lithium batteries.</p> |
