The historical development of the discovery of aromatic molecules and their unique properties

Examples of an electrocyclic + cycloaddition pericyclic cascade, and examples of sigmatropic migrations.

Examples of cycloaddition reactions illustrating both supra and antarafacial modes and endo/exo isomerism.

Statement of the four main pericyclic selection rules in terms of transition state aromaticity. Examples of electrocyclic reactions.
