    Abstract: A process for preparing a halogenoalkylsulfonamide derivative represented by the general formula (I):
    wherein R 1 is alkyl, hydroxyalkyl, cycloalkyl, or phenyl which may have alkyl, alkoxy, halogen, hydroxyl, trifluoromethyl, nitro and amino; R 2 is hydrogen atom, alkyl, hydroxyalkyl, cycloalkyl, or phenyl which may have alkyl, alkoxy, halogen, hydroxyl, trifluoromethyl, nitro and amino; X is chlorine, bromine or iodine; and Y is alkylene group having 5 to 12 carbon atoms; an intermediate; and a process for preparing the intermediate. The amide derivative is a useful compound as an intermediate for preparing a diazacycloalkanealkylsulfonamide derivative, which has antiallergic activity and thereby is useful as a medicament for preventing and treating diseases such as bronchial asthma, allergic rhinitis, atopic dermatitis, urticaria, and the like.

    Abstract: Described is the preparation of fluorooxy-fluorosulfonyl com­pounds by direct fluorination of β-sultones with elemental fluorine according to the reaction scheme:
    wherein
    R₁ and R₂, the same or different from each other, represent fluorine or chlorine or an alkyl radical partial­ly or completely halogenated with fluorine and/or chlorine.
    The reaction is conducted continuously in the presence of a fluorination catalyst, preferably an alkali-metal fluoride, at temperatures of from -40°C to +100°C and at pressures of from 50 to 800 kPa.

    Abstract: The invention concerns a method for synthesis of hydrogenofluoromethylenesulphonyl radical derivatives, comprising: a) a step which consists in condensing a thiolate (that is a monoalkyl sulphide salt) with a compound having a sp3 hybridized carbon bearing a hydrogen, a fluorine, a heavy halogen selected among chlorine, bromine and iodine and an electron-attracting group selected among fluorine and those whereof the σp is not less than 0.2, advantageously than 0.4; b) a step which consists in oxidizing the compound obtained in step a). The invention is applicable to the synthesis of various compounds having a suphinyl or sulphonyl group.
