In addition to Diels-Alder and hetero-Diels-Alder reactions, tetrafluoro-o-benzoquinone (o-fluoranil) undergoes nucleophilic additions, addition-eliminations, dioxole formation, and charge-transfer complexation, reacting at every site on the molecular skeleton. It also effects dehydrogenations and other oxidations. The quinone can function as a (CF)(4) synthon.

The photolysis of 1,2-di-iodotetrafluorobenzene in the presence of benzene and benzene–hexane mixtures gives products derived from the 2-iodotetrafluorophenyl radical and from tetrafluorobenzyne. The aryne product, 5,6,7,8-tetrafluoro-1,4-dihydro-1,4-ethenonaphthalene, is photoisomerised in part to tetrafluorobenzocyclooctene(2).
