(4n+2) Hückel rule and some polycondensed systems

  • Published:
Bulletin of the Academy of Sciences of the USSR, Division of chemical science Aims and scope

Conclusions

  1. 1.

    The (4n+2) Hückel rule does not hold for regular coronenes-m,l.

  2. 2.

    The (4n+2) Hückel rule is fulfilled for unbranched cis-condensed cyclopentadienyl systems.

  3. 3.

    The Hückel rule is not fulfilled for the transcondensed cyclopentadienyl systems: vacant bonding levels exist for all such systems.
