Abstract

The present invention relates to a method for preparing organic fluorocompounds, more particluraly to a method for preparing organic fluorocompounds by means of reaction of alkyl halide or alkyl sulfonate with fluoro salt in the presence of imidazolium salt as a solvent or mixture solvent of imidazolium salt and oragnic solvent. Such a method reduces the reaction time and improves the yield considerably by being accomplished under a mild reaction condition, such that the organic fluorocompounds can be prepared in an economic manner.
