Theoretical calculations of this property can be done using the Pariser-Parr-Pople method, and it can be verified experimentally by observing a ring current.
A general class of reactions for compounds with this property includes the Bamberger rearrangement and the Smiles rearrangement, while substituents to systems with this property can be modified using a copper salt in the Sandmeyer reaction. Theoretical calculations of this property can be done using the Pariser-Parr-Pople method, and it can be verified experimentally by observing a ring current. Coronene displays this property, while cyclo-butadiene does not, despite both of them violating the 4 n plus 2 rule of it named for H?ckel. For 10 points, name this property seen when a planar pi system is stabilized by extensive conjugation, as in certain odiferous compounds.
