    • The invention pertains to a process for preparing compounds of formula (I-A) or (I-B) here below: by reaction of perfluoroallylfluorosulfate (FAFS) of formula (II): with at least one hypofluorite of formula (II-A) or (II-B): wherein: RF in formulae (I-A) and (II-A) is a monovalent fluorocarbon C1-C20 group, optionally comprising oxygen catenary atoms, optionally comprising functional groups comprising heteroatoms (e.g. -SO2F groups); R'F in formulae (I-B) and (II-B) is a divalent fluorocarbon C-1-C6 group, preferably a group of formula (III): wherein X1 and X2, equal to or different from each other, are independently a fluorine atom or a C1-C3 fluorocarbon group. The FAFS-hypofluohte adducts of formulae (I-A) and (I-B) can be produced with high selectivity so as to access useful intermediates which can further be reacted taking advantage of the un-modified fluorosulfate group chemistry.
    • 本发明涉及制备下式(IA)或(IB)化合物的方法:通过式(II)的全氟烯基氟代硫酸盐(FAFS)与至少一种式(II-A)或(II- B):其中:式(IA)和(II-A)中的RF是任选地包含氧链原子的单价碳氟化合物C1-C20基团,任选地包含包含杂原子(例如-SO 2 F基团)的官能团; 式(IB)和(II-B)中的R'F是二价碳氟C 1 -C 6基团,优选式(III)的基团:其中X 1和X 2彼此相同或不同,独立地为 氟原子或C1-C3氟碳基团。 式(I-A)和(I-B)的FAFS-次氟酸加合物可以以高选择性生产以获得有用的中间体,其可以利用未改性的氟代硫酸盐基团化学物质进一步反应。

    • A production process of a fluorosulfuric acid aromatic-ring ester according to the present invention includes reaction of an aromatic-ring hydroxyl compound with sulfuryl fluoride (SO 2 F 2 ) in the presence of a tertiary amine except pyridine and methylpyridine. The sulfuryl fluoride, used as the reactant in the production process according to the present invention, is widely adapted as a fumigant and is easily available on a large scale. Further, the target compound can be obtained rapidly with a high yield under moderate reaction conditions in the production process according to the present invention. In this way, all of the prior art problems can be solved in the production process according to the present invention. The production process according to the present invention is thus particularly useful for industrial production of the fluorosulfuric acid aromatic-ring ester.
    • 根据本发明的氟代硫酸芳环酯的制备方法包括在除了吡啶和甲基吡啶之外的叔胺存在下,芳环羟基化合物与硫酰氟(SO 2 F 2)的反应。 在根据本发明的生产方法中用作反应物的硫酰氟被广泛地用作熏蒸剂,并且容易获得大量。 此外,在本发明的制备方法中,在中等反应条件下,可以快速获得目标化合物。 以这种方式,可以在根据本发明的制造方法中解决所有现有技术问题。 因此,根据本发明的制备方法对于工业生产氟代硫酸芳环酯特别有用。
