Conclusion

  1. 1.

    Nitroarylazo-and bis(arylazo)cyclooctatetraenes upon electron impact form molecular radical-cations. The eight membered ring in these species does not transmit conjugation.

     
  2. 2.

    The major fragmentation pathways of the molecular ions consist of the cleavage of the bonds between nitrogen and the carbon atom of the cyclooctatetraene ring.

     
  3. 3.

    The fragmentation of the ions of several arylazocyclooctatetraenes proceeds with the contraction of the eight-membered ring to a six-membered ring.
