  • Stereoselective method for preparing a chiral fluorinated molecule
    Patent number: 7619111
    Abstract: A stereoselective method for preparing a chiral fluorinated molecule by converting a compound having a —OSOF group, a fluorosulfite, attached to a chiral carbon atom into a fluorinated compound by replacing the —OSOF group attached the chiral carbon with a fluorine atom where the compound having the fluorine atom in place of the —OSOF group has an inverse configuration relative to the —OSOF group.
    Type: Grant

    Date of Patent: November 17, 2009
    Assignee: Rhodia Chimie
    Inventors: Joseph Lopez, Gérard Rajoharison, Jean-Serge Ferlut
  • Stereoselective Method for Preparing a Chiral Fluorinated Molecule
    Publication number: 20080071108
    Abstract: A stereoselective method for preparing a chiral fluorinated molecule comprising: (i) introducing a fluorosulfite compound having a C*-OSOF unit into a reactor; (2i) conducting thermal decomposition of said compound in the presence of a nucleophilic catalyst; and (3i) recovering the resultant fluorinated molecule having a C*-F unit in the inverse configuration relative to the starting C*-OSOF unit.

  • Process for the preparation of perfluoroalkanols
    Patent number: 4761506
    Abstract: A process is disclosed for the preparation of perfluoroalkanols by reacting an ester of a perfluorinated acid in the liquid phase with hydrogen under a pressure of between about 1 and 300 bars in the presence of a catalyst based on at least one metal selected from nickel, cobalt, copper and the metals of the platinum group. The perfluoroalkanols are employed as synthesis intermediates in the pharmaceutical and plant-protection industries.
