unsaturated products. These were identified by oxidation and other studies as 3H:4H- and 4H:5H-octafluorocyclohexene, 1H-1:4-, 1H-1:3-, and 2H-1:3-heptafluorocyclohexadiene, and hexafluorobenzene,2 thus indicating a 1H:2H:4H-structure for the saturated precursors. The stereochemistry of the adjacent > CHF groups was established by resolution, via the brucine salt, of the 3H:4H-hexafluoroadipic acid obtained
