Abstract
The direction of the reaction between substituted perfluorobenzenes and thioacetic acid depends on the location of the substituents in perfluoroaromatic ring. Hexafluorobenzene reacts at positions 1 and 4, perfluoro-m-xylene reacts at positions 4 and 6, while perfluoroindane reacts at positions 5 and 6 to give the corresponding dithiols with para-, meta- and ortho-location of the thiol groups, respectively. Domino-reaction of perfluoroindane-5-thiol and its acetyl thioester affords hexadecafluoro-2,12-dithia-pentacyclo[11.7.0.03,11.05,9.015,19]icosa-1(13),3,5(9),10,14,19-hexaene
