Method for producing oxysulphidic and fluorinated derivatives in ionic liquid medium

The invention relates to a method for producing an oxysulphidic and fluorinated derivative in the form of a salt of formula (II) Ea-SOO-Q+ (II) comprising providing an ionic liquid compound of formula (I) in the liquid state Ea-SOO-Q+ (II) - Ea representing the fluorine atom or a group having between 1 and 10 carbon atoms selected from fluoroalkyls, perfluoroalkyls and fluoroalkenyls; and - Q+ representing an onium cation, with a sulphur oxide, said ionic liquid compound of formula (I) representing at least 50 wt. % of the initial liquid reactive medium. 本发明涉及种用于生产具有式(II)Ea-SOOQ(II)的以盐形式的氧硫化物和氟化衍生物的方法，该方法包括提供呈液态的具有式(I)Ea-SOOQ(II)的离子液体化合物与氧化硫，-Ea表示氟原子或选自氟烷基、全氟烷基以及氟烯基的具有在1与10个之间碳原子的基团，并且-Q表示鎓阳离子，所述具有式(I)的离子液体化合物表示初始液体反应性介质的至少50wt.％。
