Abstract (en)
[origin: WO2019229359A1] The present invention concerns a method for preparing a compound of the following formula (III): R2-(SO2)-NM-(SO2)-F (III) in which R2 represents one of the following radicals: F, CF3, CHF2, CH2F, C2HF4, C2H2F3, C2H3F2, C2F, C3F7, C3H4F3, C3HF6, C4F9, C4H2F7, C4H4F, CF11, C6F13, C7F1, C8F17 or C9F19; M represents a monovalent or divalent cation; the method comprising: - a step b) of fluorinating a compound of the following formula (I): R1-(SO2)-NH-(SO2)-Cl (I) in which R represents one of the following radicals: Cl, F, CF3, CHF2, CH2F, C2HF4, C2H2F3, C2H3F2, C2F, C3F7, C3H4F3, C3HF6, C4F9, C4H2F7, C4H4F, CF1 1, C6F13, C7F15, C8F17 or C9F1 9, R preferably representing Cl; with at least one fluorinating agent; 2 - a step c) of distilling the composition obtained in step b).
