  The thermal isomerization of [2a,11-13C2]dicyclopenta[ef,kl]heptalene (azupyrene) to pyrene

  摘要：

  [2a,11-C-13(2)]Dicyclopenta[ef,kl]heptalene (azupyrene) has been synthesized from [1,2-C-13(2)]cyclopentanone which, in turn, was prepared from C-13-labeled cyanide and C-13-labeled iodomethane. Thermal isomerization of the labeled azupyrene gave [3a,11-C-13(2)]pyrene. The only proposed mechanisms consistent with this result are the radical-initiated methylene walk and that involving a peripheral bicyclobutane intermediate. These mechanisms are also in agreement with previous results from the isomerization of 1-methylazupyrene except for an additional minor product in the latter experiment. Evidence for the automerization of pyrene under the thermal isomerization conditions has been obtained.
