  Pyrolysis transformed the title diene (1) into a 9:1 mixture of perfluorobicyclo[3.1.1]heptane (2) and cis-perfluorobicyclo[3.2.0]heptane (3) at 300 degrees C and at > 450 degrees C principally into perfluarocyclopentene (11). Mercury-sensitized vapor phase photolysis of 1 also yielded 2 and 3, but the latter now dominated and its trans isomer 13 was formed as well. In the presence of nitrogen as a bath gas, the product was further enriched in the [3.2.0] isomers. Radical bromination of 1, a model reaction for the triplet photocyclization, gave cis- and trans-perfluoro-1,2-bis(bromomethyl)cyclopentane (IB). Configurations were assigned to the cis and trans isomers of perfluoro-1,3,6-heptatriene (19 and 20), and they were equilibrated with iodine/visible light (K-t-->c = 1.6(7) in CDCl3, 14 degrees C). The cis triene underwent electrocyclization at 133 degrees C to perfluoro-3-allylcyclobutene (27); thermal ring opening of this cyclobutene yielded exclusively the cis isomer. At 250 degrees C both the cis triene and the allylcyclobutene were transformed quantitatively into perfluorobicyclo[3.1.1]hept-2-ene (28). Trans triene gave no detectable cyclobutene over a range of temperatures, but yielded the [3.1.1] compound at 250 degrees C. Ultraviolet irradiation of cis triene produced the allylcyclobutene, and mercury photosensitization of either compound (or the trans triene) proceeded a step farther to give tricycloheptane valence isomers (31 and 32). The internal [2 + 2] cycloadditions described here contribute to our knowledge of the ground rules for reactions of this type in unsaturated fluorocarbons.
