<p>A method of making TFPX using an SN2 type nucleophilic displacement reaction. The method includes reacting a nucleophilic fluorine molecule with a nonfluorinated-tetrahalo-p-xylene molecule. Exemplary nucleophilic fluorine molecules include, but are not limited to, CsF, KF, NaF and LiF. The nonfluorinated-tetrahalo-p-xylene molecules may include, α,α,α',α'-tetrachloro-p-xylene, α,α,α',α'-tetrabromo-p-xylene or α,α,α',α'-tetraiodo-p-xylene. The reaction may be carried out in an open or closed container. Furthermore, the reaction may be carried out in the presence of a phase transfer catalyst. In certain embodiments, the reaction is carried in a substantially solvent-free environment.</p> |
