摘要：
The invention relates to a fluorination process for producing fluorinated compounds.The process consists in reacting a compound (I) corresponding to the formula with an ionic fluoride of a monovalent cation. M represents H, an alkali metal, a quaternary phosphonium group or a quaternary ammonium group. Y represents SO2 and m is 1, or else Y is PO and m is 2. Z represents CR2, N or P. R1 represents an electron-withdrawing group which has a Hammet σP parameter of greater than 0.4. R2 represents a carbonaceous and/or electron-withdrawing group. X represents a halogen other than a fluorine. The fluorinated compounds obtained are of use in particular as electrolytes in lithium batteries.
