Abstract
A method for the synthesis of TFPX-dichloride is disclosed. The method involves reacting hexachloro-p-xylene with anhydrous HF in an inert organic solvent. The reaction is advantageous in that it produces relatively high yields of TFPX-dichloride, provides little waste, and is carried out as a simple, one-step process.
