investigated. The reactions of tetrafluorobenzyne with 2-methyl- and
2,5-dimethylfuran gave the expected Diels–Alder adducts (dihydro-tetrafluoroepoxinaphthalene
derivatives) which on treatment with butadiene
afforded 9-methyl- and 9,10-dimethyltetrahydrotetrafluoroanthracenes.
Further reactions with tetrafluorobenzyne followed by dehydrogenation
gave 9-methyl- and 9,10-dimethyloctafluorotriptycenes which were used
to study new examples of long-range 19F–1H spin–spin coupling 1H NMR spectroscopy. [Continues.]
