One way to make potassium fluoride is to react the hydroxide with hydrofluoric acid. We have found the new nucleophilic fluorination reaction of some halo- and mesylalkanes to the corresponding fluoroalkanes with KF in the presence of [bmim][BF4] under various reaction conditions. In potassium fluoride, the potassium atom donates an electron and the fluorine atom takes an electron. So, it burns with fluorine, F2, to form potassium(I) fluoride, KF. In this way, potassium fluoride is recyclable. The compound formed by the electrostatic attraction of the positive ion and a negative ion is recognized as an ionic compound. Whereas the fluorination of the mesylate 1 with KF in an organic solvent such as CH3CN at 100 degrees C occurred hardly even after 24 h, the same reaction in ionic liquids, [bmim][BF4], as a reaction solvent was completed within 1.5 h, affording the wanted product 2-(3-fluoropropoxy)naphthalene 2a (85%) together with the alkene byproduct 2c (10%). [3] Such reactions usually employ polar solvents such as dimethyl formamide, ethylene glycol, and dimethyl sulfoxide.[6]. Ionic. Potassium chloride is ionic as are all potassium compounds.
