METHOD FOR PREPARING OXYSULPHIDE AND FLUORINATED DERIVATIVES IN THE PRESENCE OF AN ORGANIC SOLVENT

The present invention concerns a method for preparing an oxysulphide and fluorinated derivative of formula (III) Ea-SO3R (III) that comprises bringing a compound of formula (II) Ea-SOOR (II)—Ea representing the fluorine atom or a group having 1 to 10 carbon atoms chosen from the fluoroalkyls, the perfluoroalkyls and the fluoroalkenyls; and—R representing hydrogen, a monovalent cation or an alkyl group; into contact, in the presence of a polar aprotic organic solvent, with an oxidising agent.

Recyclable Trifluoromethylation Reagents from Fluoroform

We present a strategy to rationally prepare CF3- transfer reagents at ambient temperature from HCF3. We demonstrate that a highly reactive CF3- adduct can be synthesized from alkali metal hydride, HCF3, and borazine Lewis acids in quantitative yield at room temperature. These nucleophilic reagents transfer CF3- to substrates without additional chemical activation, and after CF3 transfer, the free borazine is quantitatively regenerated. These features enable syntheses of popular nucleophilic, radical, and electrophilic trifluoromethylation reagents with complete recycling of the borazine Lewis acid.

METHOD FOR PREPARING A SULFONIMIDE COMPOUND AND SALTS THEREOF

The present invention relates to a method for preparing an aqueous sulfonimide compound of the formula (Rf1—SO2) (Rf2—SO2)NH, wherein Rf1et Rf2 are independently selected from the group comprising: a fluorine atom and groups having 1 to 10 carbon atoms selected from the perfluoroalkyl, fluoroalkyl, fluoroalkenyl and fluoroallyl groups, from a mixture M1 including (Rf1—SO2)(Rf2—SO2)NH, Rf1SO2H and/or Rf2SO2H, Rf1SO2NH2 and/or Rf2SO2NH2, characterized in that said method includes an oxidation step of said mixture M1 using an oxidizing agent in order to obtain a mixture M2 including (Rf1—SO2)(Rf2—SO2)NH, Rf1SO3H and/or Rf2SO3H, and Rf1SO2NH2 and/or Rf2SO2NH2.
