EXAMPLE 33 This example and the following two examples illustrate the use of the complexes of the invention for “Halex”-type chlorine→fluorine exchanges in which the complex is used in a stoichiometric amount so as to allow reactions which are impossible with the prior art owing to the sensitivity of the substrates to the elimination reactions.20 g of epichlorohydrin and 44 g of K⁺[C₂H₅C(CH₂O)₃BF]^-, which is the adduct formed by the IB-2 compound with KF, are added to 150 ml of DMF and brought to 85° C. KCl is gradually formed and the reaction mixture is filtered after two hours of stirring. 14 g of epifluorohydrin (88% yield) are obtained by precipitation from 500 ml of water and then filtration.
