Versuchsvorschrift
A mixture containing 29.4 grams (0.2 mole), of ortho-dichlorobenzene, 50 grams (0.2 moles) of hexachloropropylene and 2.5 grams of ferric chloride in 250 milliliters of perchloroethylene was heated and stirred by the process of Example I for about 4 hours at reflux (125° C.). The reaction mixture was then washed with concentrated hydrochloric acid, then water and distilled to give a 48.7% yield of hexachloroindene. The product was confirmed by infrared and NMR spectra analysis as structured.
