Abstract
The invention features the use of flourosulphonates to release the organic bases from their fluorohydrate. This use is characterised in that a hydrogenofluorosulphonate of an organic base is formed and in that the hydrofuoric acid which is associated with the said base or with one of its precursors is separated therefrom. The invention is useful in organic synthesis applications.
Claims7
