%X Flash vacuum pyrolysis (f.v.p.) of &#91;2,3-13C2&#93;triphenylene-2,3-dicarboxylic anhydride (c. 22&#183;5% 13C2) at 950&#176;C gave a pyrolysate which was analysed by 13C n.m.r. spectroscopy. The principal product was &#91;2,3-13C2&#93;triphenylene. The second major product was a 1 : 2 : 1 mixture of &#91;4,7- 13C2&#93;-, &#91;4,6-13C2&#93;- and &#91;5,6-13C2&#93;-cyclopent&#91;hi&#93;acephenanthrylene.
