Tetrafluoro‐ p ‐xylylene (3) has been generated by flash vacuum pyrolysis of octafluoro[2.2]paracyclophane (2) and subsequent trapping of the products in solid argon at 9 K. Xylylene 3 photochemically rearranges to the ring‐expanded heptafulvene 5 . Matrix‐isolated species have been identified by comparison of experimental and calculated IR spectra. The temperature‐dependence of the thermal fragmentation of paracyclophane 2 has been determined by mass spectrometric analysis of the pyrolysis products.
