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-

1,1,2,2,9,9,10,10-Octafluoro-para-cyclophane was obtained by the pyrolysis of α,α'-di-bromo-α,α,α',α'-tetrafluoro-p-xylene using argon as the diluent with further trapping of the pyrolysis products in boiling toluene.The pyrolysis zone was filled with a copper packing to bind bromine.An efficient scheme was also developed for the preparation of α,α'-dibromo-α,α,α',α'-tetrafluoro-p-xylene starting from p-xylene.
