Abstract

Annulenes were studied using the concept of aromatic stabilization.
A simple expression is presented for the calculation of
aromatic stabilization of annulenes. The index of aromatic stabilization
differentiates correctly between the [4n + 2] - and [4n]
-annulenes. The analysis of the approach of Kruszewski and
Krygowski shows that their KK index differs only by a constant
from the value of aromatic stabilization of a particular annulene.
Similarly, the relation between REPE values of Hess and Schaad
and indices of aromatic stabilization is discussed.
