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.
